NetVanta 7000 Series Release Notes R10.8.1 Introduction
Copyright © 2013 ADTRAN, Inc. 4
Introduction
AOS version R10.8.1 is a maintenance release that also addresses customer issues that were uncovered in
previous code releases.
This release is generally available code. Results obtained during internal testing have been evaluated and
the code has been determined to be ready for general availability. Caveats discovered during testing but not
addressed in this build are listed in Errata - System Management on page 10.
A list of new or updated documents for this release appears in Documentation Updates on page 13.
Configuration guides, white papers, data sheets, and other documentation can be found in the ADTRAN
Support Community, https://supportforums.adtran.com. The contents of these release notes will focus on
ADTRAN’s IP telephony products.
Supported Platforms
The following platforms are supported in AOS version R10.8.1.
• NetVanta 7100 – IP Communication Platform
• NetVanta 7060 – IP PBX
For a list of the software and firmware requirements, refer to the table in Minimum Software or Firmware
Required for Interoperability on page 6.
To confirm the Boot ROM version of the ADTRAN unit, telnet or console to the unit and issue the show
version command. In the command output, the Boot ROM version will be listed as Boot ROM version
XX.XX.XX. If you require a Boot ROM upgrade, please contact ADTRAN Technical Support
([email protected] or 888-423-8726) for assistance.
Hardware Requirements and Limitations
In an effort to maximize customer experience, whenever possible and applicable, ADTRAN will advertise
the minimum hardware requirements for running the recommended software versions. While ADTRAN
strives to support the newer software revisions on existing hardware, due to CPU, RAM, and other
hardware limitations, it may not always be possible. In such instances, customers are advised to upgrade
the hardware (including phones, NetVanta 7000 Series chassis, and accompanying networking gear) while
upgrading their software, because performance issues and erratic behavior could cause certain product
features to become nonfunctional. ADTRAN provides field advice whenever possible in these cases.
Resellers and customers are advised to periodically check with ADTRAN Technical Support and field staff
for these advisories, especially when upgrading to newer software revisions.
NetVanta 7100 Hardware
New features included with any AOS release warrant some attention before use by the customers,
specifically the choice of the hardware platform on which the new AOS version will be installed.
There have been two revisions of NetVanta 7100 hardware. These are denoted by different part numbers:
1200796L1 (older) and 1200796E1 (newer). Beginning with AOS release A2.04, ADTRAN does not
recommend using newer AOS versions on the older 1200796L1 units. These units continue to be field

NetVanta 7000 Series Release Notes R10.8.1 Hardware Requirements and Limitations

worthy and would continue to perform as expected for their useful lifetime on software revisions prior to
A2.04. However, due to differences in hardware, some or all of the new features might not be supported on
the older hardware (1200796L1).
The 1200796L1 is explicitly NOT recommended for use for the following features or firmware releases:
• For any firmware release R10.x or higher
• Support for greater than 50 users. DSP resources were increased on 1200796E1 units, allowing additional
TDM to IP conversions. The user limit on the 1200796L1 remains unchanged.
• SIP trunks that require the NetVanta 7100 to perform transcoding. This conversion is required if the SIP
trunk provider does not support G.729.
• Use of the Echo Return Loss (ERL) tool.
While there are no further known constraints for other features at this time, keep updated on any future
advisory by ADTRAN. The recommended hardware for the AOS A2.05 and later features is 1200796E1.
Contact your ADTRAN representative about the options available to you if you have a 1200796L1 unit,
and want to use a newer release.
IP Phone Models
Beginning with release A4.x, the legacy Polycom phones (IP 430, IP 501, IP 601 and IP 4000) do not
support all the features available in the current AOS and phone firmware releases. Customers could
experience sluggish behavior on these older generation phones when used in conjunction with newer
software releases. If you experience sluggish behavior after an upgrade, contact ADTRAN Technical
Support for a solution. This could involve either upgrading the phone hardware (to the equivalent newer
generation phone, such as IP 450, IP 550, IP 650, or IP 6000) or scaling back the feature load on the legacy
phones.
ADTRAN branded VVX phones (model names ADTRAN VVX 300, ADTRAN VVX 310, ADTRAN
VVX 400, ADTRAN VVX 410, ADTRAN VVX 500, and ADTRAN VVX 600) work with NetVanta
7000 series AOS release version R10.8.0 and beyond without requiring an additional license key purchase.
The equivalent Polycom branded phones will not work with release R10.8.0. If you are currently using the
equivalent Polycom branded phones with the NetVanta 7000 series, you will need to either remain on a
pre-R10.8 release version or use the ADTRAN branded version of the VVX phones until a licensing
mechanism can be added to allow the use of Polycom branded VVX models.
The rest of the Polycom family of supported IP end points continue to remain unaffected. Either an
ADTRAN branded model or the equivalent Polycom branded models of these IP phones can be used with
R10.8 and beyond. See the following table to determine AOS release R10.8 compatibility with ADTRAN
and Polycom branded phone models.
Table 1. Release R10.8 Phone Compatibility

Software Requirements and Limitations
This section defines the recommended firmware/software versions necessary for the related aspects of the
NetVanta Unified Communications solution.
AOS Firmware Image Storage
AOS firmware images can be stored on flash/non-volatile random access memory (NVRAM) as well as on
CompactFlash®memory. However, it is recommended that the primary firmware image be stored on
flash/NONVOL and the backup firmware be stored on CompactFlash.
To copy the current image from flash/NVRAM to CompactFlash, use the copy flash <filename> cflash
<filename> command.
Required AOS Bootcode Version
When upgrading to AOS version R10.8.1, an upgrade to bootcode version A2.06.B1.01 is required. Check
the table in Minimum Software or Firmware Required for Interoperability on page 6 to verify you have the

Important Notices
The following important notices are provided in addition to the previous Supported Platforms, Hardware
Requirements and Limitations, and Software Requirements and Limitations sections to ensure successful
deployment.
Upgrades to AOS version R10.8.0 and Later
Beginning with AOS version R10.8.0, the syntax of certain commands was modified from previous AOS
versions (such as AOS R10.5.x, R10.7.x) by either removing or adding the ip keyword. In general, when
the ip keyword appears in a command, it signifies that the command is only applicable to IPv4
functionality. As more features introduce IPv6 support, the ipv6 keyword is added to signify the command
is only applicable to IPv6 functionality. The ip keyword has been removed from several commands to
signify that the command has both IPv4 and IPv6 functionality.
Due to this syntax change, downgrading a NetVanta 7000 Series product configured in AOS version
R10.8.0 or higher to a previous AOS version (such as AOS R10.5.x, R10.7.x), could cause service
disruption because the new syntax might not be recognized by the previous version. Upgrading a unit from
an older AOS version to AOS version R10.8.0 or later will not cause service disruption because both the
old and the new syntaxes are accepted. It is recommended that a full copy (data and voice settings) of
the configuration be saved prior to upgrading to AOS R10.8.0 and above. This can be done from the
Utilities > Configuration page in the GUI.
For more information on specific commands, refer to the AOS Command Reference Guide available at
https://supportforums.adtran.com.
Please note that the NetVanta 7000 series does not support IPv6 at this time. If you envision needing any
IPv6 features natively on the NetVanta 7000 series, then contact your ADTRAN representative with your
request. In general, we recommend using an IPv6 capable ADTRAN router with the NetVanta 7000 series
for any IPv6 features.
Default Firewall Configuration Changes
Changes were made to the default firewall configuration to increase security of voice platforms when
connected to the Internet. These changes can impact remote phones and SIP trunking applications, but do
not impact local phones on the NetVanta 7000 Series.
• In AOS versions A2.01.00 through A2.03.00.SC, the default Public access control policy (ACP) allowed
SIP traffic (destined for UDP port 5060) inbound. For AOS A2.04.00.SC and above, this traffic is no
longer allowed by the factory default configuration. Instead, the installer is required to selectively
customize the Public ACP to allow SIP traffic from remote sites and SIP trunking providers.
• Units that were shipped with AOS versions through A2.03.00.SC contain a default configuration that
allows inbound SIP traffic (destined for UDP port 5060). These configurations should be modifiedbefore

deployment. Guidelines for this configuration are given in the NetVanta 7000 Series Security Guide
available from the ADTRAN Support Community, https://supportforums.adtran.com.
Notice of Defined Voicemail File Limit
The NetVanta 7000 Series products can maintain a maximum of 3000 voicemails per system. The
implementation of voicemail message expiration allows the system to remain within the defined limit.
Upgrading the CompactFlash card to a larger card is not supported and will not result in more voicemail
storage. Should you need to replace a failed CompactFlash card, contact ADTRAN Technical Support for
assistance.
Updates to Web Interface Pages
On occasion, changes are made to web pages in the NetVanta 7000 Series web interface that may require
files in the browser cache to be purged. This can be done in most browsers by deleting the browsing history
or by pressing Ctrl-F5 in most cases.
Considerations Before Upgrading Related to SPRE Code Support for SLA
1. Local SPRE code dialing from an SLA requires phone dial plan changes. After upgrading to R10.6.0
software, newly created phone configurations will have the proper dial plan settings applied. For upgrade
cases where SLA was already configured on an existing phone, the dial plans will be modified to support
this new functionality. Please review the changes under the IP Phone configuration page and regenerate
the phone configurations by using the admin login and browse to Voice>IP Phone Globals>Default
Settings>, select “New and Existing Configurations” and select Apply.
2. SPRE code dialing from an SLA could interfere with existing configurations if SPRE codes were used
on SLA’s prior to this release. Plese review your configuration to determine if SPRE codes were allowed
prior to the upgrade (check SLA dial plans) and if so, you will need to configure the following command
voice spre-mode override <*xx> using the appropriate codes in place of xx.
NetVanta 7100 Security Vulnerability
Summary
This security update resolves privately disclosed vulnerabilities in ADTRAN's NetVanta 7100 that can
occur with the 7100 GUI login page. The resolution included code changes to suppress echoing injections.
Also addressed was a potential exploit of a SSL renegotiation.
This security update is rated Critical for the NetVanta 7100.
Recommendation
Customers should upgrade to R10.8.1. Go to the NetVanta 7000 firmware page to download this AOS
release.

System Notes
This section outlines known caveats for AOS version R10.8.1.
Features and Enhancements
No new features or enhancements were included in this release.
Fixes
This section highlights major bug fixes in AOS version R10.8.1.
•Thematch ani command used for ANI substitution will match on the received ANI prior to any global
ANI substitutions. The match ani command used for adding or substituting diversion headers will match
on the modified ANI after the global ANI substitutions are applied.
• During conferences that use the conference bridge in UC Server, when one member in a conference
places the call on hold, music may stream to all members that have joined the conference.
• Caller ID does not display on pickup *52xxxx*.
• The Personal Phone Manager's User Status monitoring list may return the list from the previous user's
browser session if more than one user shares the desktop browser.
The work around is to delete all cookies and restart the browser.
• Calls with caller IDs that contain special characters can be disconnected when placed on hold by an
Advatel IP Console.
• Adding a T1/E1 link to an existing Multilink PPP bundle using the GUI causes the PPP link to bounce
when applied. The PPP link will go down and immediately recover; however, some packets could be lost.
Towork aroundthis issue,a T1/E1can beadded usingthe CLI,and the link will stay up while the addition
is applied.
• Calls using the G.729 CODEC are limited to 25 calls for E1 PRI.
• FindMe-FollowMe treats all calls from the auto attendant as internal calls.
• SNOM M3 phones do not support attended transfer at this time. This and other caveats will be
documented in a future configuration guide for using the SNOM phones with the NetVanta 7000 Series.
• The GUI IP Phone Configs Update Directories command would only merge the first 21 system directory
entries.
•Thefactory-default command would not change the Primary System Configuration file to the startup
configuration if it had changed.
• Manually editing phone configuration files resulted in the phones disappearing from the IP Phone
Configs GUI page.
• Paging group calls originating from ADTRAN IP 7XX phones had no audio.
• When using auto-link over HTTPS in AOS R10.8.0, check-ins would fail.
• Forwarded voicemail messages reported a date one month previous from the actual date of the message.

NetVanta 7000 Series Release Notes R10.8.1 Errata - System Management
Copyright © 2013 ADTRAN, Inc. 10
Errata - System Management
The following is a list of System Management errata that still exist in AOS version R10.8.1.
• Incoming SIP trunk calls that were locally transferred would stop remote ringback during any subsequent
coverage.
• A 503 Service Unavailable response was received when attempting to edit a trunk account.
• The NetVanta 7100 rebooted when attempting a transfer during heavy call loads.
• Hot desking configuration files only supported the use of the default VLAN 2 IP address, 10.10.20.1.
• Click-to-Dial calls in a NetVanta BCS configuration were not being dialed.
• TFTP client connections caused memory to be lost and not recovered.
• Attempting to use a pickup group to pick up a call queue resulted in the call being dropped.
• When an external call was transferred to an internal extension which was configured for coverage to an
external number, the diversion header was missing when the call was routed back out to the external
number.
• An inbound ring group call that was cleared too quickly resulted in a reboot.
• When Music-on-Hold was set to external, Polycom IP phones were not able to blind transfer a call.
• Under heavy call load it was possible that successive calls could use the same memory location to store
their B-channel information, which caused a reboot when the latter call disconnected.
• Enabling VQM caused audio to be lost when using the Simple Remote Phone feature.
• The NetVanta 7100 and NetVanta 6355 platforms will fail to reset QoS map statistics for applied QoS
maps when the clear counters command is executed.
• When adding a new user account, the GUI may incorrectly display an FXS port as available when it is
already assigned.
• The CLI command, no description, cannot be used to remove a description from a ring group
configuration.
• If an attempt is made to configure greater than the maximum number of call queues, an error will be
shown. Following this error,no call queue configuration commands can be entered until theconfiguration
mode is exited.
• The Startup Wizard does not present an error message if an invalid VLAN ID is entered when configuring
the Data and Voice VLAN tags.
• An HTTP timeout does not output the correct string in the CLI. Instead a %s is substituted.
• Adding a description to a status group on the Status Groups menu of the GUI may result in a 503 Service
Unavailable response.
• After upgrading from A4.X or A5.X to R10.2 or later the GUI does not highlight Polycom IP 550/560
phones to indicate the phone configuration requires updated.
• When creating a new user in the GUI, DID numbers and aliases are not saved if the Edit Config button is
pressed followed by the Apply button.
• When using the GUI to configure voicemail notification for a user, the times midnight and noon are
mistakenly swapped.
• After a pickup group has been created, the pickup extension and description cannot be modified.

NetVanta 7000 Series Release Notes R10.8.1 Errata - Call Control
Copyright © 2013 ADTRAN, Inc. 11
Errata - Call Control
The following is a list of Call Control errata that still exist in AOS version R10.8.1
• Voicemail to email may fail with a socket error when using TLS.
• Invalid options are presented in the GUI drop-down menu for setting the switch type in the PRI settings.
• The Shared Line Accounts GUI menu incorrectly displays a configuration option for Codec Outbound
Group. This is not a valid configuration option.
• The GUI incorrectly states that System Mode coverage can be set to Busy, when in actuality it would use
the Default Mode coverage.
• The System Summary GUI menu is not displayed when the NetVanta 7100 is running NetVanta 6355
firmware.
• The platform displays as unknown in the GUI when the NetVanta 7100 is running NetVanta 6355
firmware.
• Auto-link client traffic may negatively impact performance because it is not being discardedunder heavy
call volume.
• When configuring the CODEC Group setting for a SIP trunk in the GUI, if <default> (G.711 uLaw) is
selected, the output of a show run in the CLI will show no codec-group is configured.
• When using Internet Explorer, the Apply button on the Voice > IP Phone Globals > Default Settings tab
will not function. Workaround: Use Firefox, Chrome, or Safari to apply changes on this GUI page.
• Inbound calls from Megapath (Broadsoft) SIP trunks fail to be delivered by FindMe-FollowMe to
external numbers. Calls roll to next Call Coverage item after being answered at the external number.
Workaround: Enable Ringback Only and disable the Accept option in the FindMe-FollowMe
configuration for the call to external party to be successful.
• Caller ID may not be correctly sent when an SLA/SCA call is transferred to an extension.
• Successive reINVITE SIP messages to place a call on hold will be rejected with a 400 Bad Request
response if incoming music-on-hold is enabled on the SIP trunk.
• transport=TCP is incorrectly included in the Contact header on a UDP SIP trunk.
• SLA accept/reject templates do not affect calls sent using the SLA.
• Call coverage set to internal will still allow calls to be routed out an external trunk.
• FindMe-FollowMe fails with Single Number Reach service in NetVanta BCS.
• When a voice user is configured for an empty caller ID number, the name is also not transmitted.
• Configuring a user to have Dialtone Only message waiting does not result in a SIP NOTIFY message to
the SIP endpoints when a new message is waiting.
• When configuring call coverage, setting the Ring Extension to Never results in a three-second delay
delivering voice traffic to the ADTRAN phone.
• A SIP Trunk configured to replace the diversion header is not correctly replacing the most recent
diversion header when multiple diversion headers are present.
• Attempting to ring external numbers through FindMe-FollowMe fails and disconnects the caller if the
press-to-accept option is disabled. Workaround: Enable the press-to-accept option for external numbers,
or alternately use the Refer the call to action for external numbers.
• Inbound calls are not correctly routed to a SIP identity when configured on an auto attendant.

Errata - Endpoint
The following is a list of Endpoint errata that still exist in AOS version R10.8.1
• Intermittent inbound calls on SLA lines ring indefinitely without the switchboard routing the call.
Workaround: Enable blind-dial for each analog trunk account.
• Transferring a call from an external SIP trunk back out the same trunk via an auto attendant action results
in a failure to populate the SDP portion of the SIP message in either the INVITE or the ACK message.
Workaround: Set the transfer-mode to network on the SIP trunk for this call flow to be successful.
• T.38 fax call tests fail after T1 PRI loss and system timing shifts. Workaround: A reboot is required to
clear the condition.
• Held Call Pickup (*78nnnn) may not have audio if the user who placed the call on hold is configured as
a simple remote phone.

audio.
• An external call from an analog phone may result in choppy hold music when placed on hold by the
analog phone.
• Extended coverage paths may cause transcoding to fail with a SIP trunk.
• If a Simple Remote Phone calls a user with FindMe-FollowMe configured as ringback only, ring
external, and press to accept, the remote phone user will not hear audio. Workaround: Disable
ringback-only in the FindMe-FollowMe configuration for the called user.
• Hairpinned calls may fail to have audio after being transferred.
• When local packet capture completes and while it is being exported, voice quality may be adversely
affected.
• During an internal SIP-to-SIP call, if the caller places the called party on hold, thenthe called party places
the caller on hold, when the caller retrieves the called party from hold both parties will experience no
audio.
• If a SIP is extension is blind transferred out an analog FXO trunk, noise is sometimes introduced in the
audio.
• A call placed to a remote user that that uses G.711 Ulaw or G.711 Alaw will result in one-way audio if
the call is routed out a trunk that contains a CODEC list.
• If the USB ID is changed or removed, it is still possible to connect a call using the cellular interface.
• An E&M Wink trunk does not correctly send dialed digits.
• Bria soft phones registered through the SIP security port always show up in the Suspect list.

• AOS Command Reference Guide
• A user account already registered (with a static registration or through the hot desk feature) to an IP phone
may log into another hot desk phone. This causes the new hot desk phone to become the active phone for
that user account. The original IP phone is no longer registered to that user account.
• Assigning the language on the Default Settings tab under IP Phone Globals GUI menu does not change
the language for Polycom SoundPoint IP phones.
• For Polycom phones running 4.x.x firmware, the User ID field on the login screen is in abc/ASCII
encoding mode by default. Workaround: Press Encoding and then select 4 to change to numeric mode.
• If ip mcast-stub fixed is removed from an interface configuration which also has an IGMP static group
configured, the mroute will not be deleted as it should. This only occurs when static groups are
configured. It does not occur with dynamically learned groups.
• The NetVanta 7100 incorrectly allows the use of Ethernet 0/1, or any other switchport, as a NAT
interface.
• The GUI of an AOS device acting as a wireless access controller can not display the software currently
running on a connected access point.
• A hostname entry in an ACL can fail to resolve to the correct IP address even though the router's host
table reflects the correct IP address. Workaround:Use IP addresses instead of a hostname when creating
an ACL.
