Network Routing Table
Press Add New or Modify to add or modify a network routing record. Input subnet as
Destination, subnet mask as Netmask, and gateway as Gateway.
Press Apply to save configuration, or press Cancel to quit configuration.
2.5.2 Extension Configuration
User has to set Extension account for other device to register on ePBX-100A-128.
Enter Configuration ÆExtension to configure Extension data. User can press
Modify to add new Extension or modify configured Extension data. Press Delete will delete
the specified Extension.

12
After press Modify can input detail setting for Extension.
Extension Number: Assign the number of Extension. This number is also the register
name for device.
Password: Assign the register password for device to register on ePBX-100A-128.
Call Group: You can use the Call Group parameter to assign an Extension to one or
more groups.
Pickup Group: You can use the Pickup Group option in conjunction with this
parameter to allow a ringing phone to be answered from another extension.
Note:
zThe Pickup Group option is used to control which Call Groups a channel may pick
up—a channel is given authority to answer another ringing channel if it is assigned
to the same Pickup Group as the ringing channel’s Call Group. By default, remote
ringing extensions can be answered with *8 or **8+ext. number.
zYou can define multiple Call Groups and Pickup Groups for one Extension by a
“comma”. For example, you can input “1,3,5” into Call Group or Pickup Group.

13
DialPlan: Define the dialing plan for Extension. It specifies the location of the
instruction used to control what the phone is allowed to do, and what to do with
incoming calls for this extension. In this field, you can Choose 5 dial level for Extension,
including [ext-only], [ext+R1], [ext+R12], [ext+R123], [ext+allroutes]. You can define an
“Outgoing call” record, to a certain Route Level, as R1, R2…, etc. [ext-only] means this
subscriber can only call to Extension. [ext+R1] means the subscriber with such
DialPlan can call to Extension and Route Level with R1. [ext+R12] means the
subscriber with such DialPlan can call to Extension and Route Level with R1 and R2.
[ext+R123] means the subscriber with such DialPlan can call to Extension and Route
Level with R1, R2 and R3. [ext+allroutes] means the subscriber with such DialPlan can
call to Extension and Route Level with R1, R2, R3 and R4.
Note:
•For more information about Route Level, please refer to the user manual:
CH3.1.6.1 Outgoing Call Rule.
Keypad: User can select Keypad type to be RFC2833, In-band, SIP-Info and Auto.
You can choose Auto to auto select the Keypad type. Choose RFC2833, Inband or
SIP-Info here will force the Extension use RFC2833, Inband or SIP-Info only and the
setting should be also match the Keypad setting of Extension device.
Note:
•Now ePBX-100A-128 could not support G729 with Inband Keypad type. If
ePBX-100A-128 detect the caller or callee not support RFC2833 DTMF type.
Then ePBX-100A will force the Codec to G711 to make sure the DTMF detection
is correctly.
NAT Traversal: If the Extension device is behind a device performing NAT, such as
firewall or router, and need to register to ePBX-100A-128 on public network, then user
has to enable this function. Enable NAT Traversal to force ePBX-100A-128 to ignore
the contact information for the Extension and use the address from which the packets
are being received.
RTP Mode: User can choose for two type of RTP mode, one is Routed Mode another
is Direct Mode. The voice media will be routed “Peer-to-Peer” if two clients are both
setting to Direct Mode. This way will improve the voice quality and reduce the
performance wastage of the ePBX-100A-128.
Note:
•If one peer set to Direct Mode but another peer set to Routed Mode, the result will
become to Routed Mode.
•Voice media will still go through the ePBX-100A-128 if the ePBX-100A-128 needs
to detect DTMF.
•If you enable the NAT Traversal function for Extension, the RTP mode will change

14
to Routed Mode directly; this way will avoid the “one-way voice” or “no voice
issue” of VoIP.
•If the both peers are under different subnet, or one peer is under Public IP but
another one is under Private IP, we strongly suggest you to set the RTP mode
to Routed Mode to avoid some unexpected voice problems.
Fixed Trunk ID: User can define a Fixed Trunk for a certain extension. When such
extension makes an outgoing call via routing table, ePBX-100A-128 will check “Fixed
Outgoing Call Rule” first. If “Fixed Outgoing Call Rule” is enabled, then
ePBX-100A-128 will confirm the Fix Trunk ID for the calling party. That means the
outbound call will be routed by Fixed Trunk ID, if you define the Fixed Trunk ID for the
calling party and you also enable “Fixed Outgoing Call Rule”.
Note:
•For more information about Fixed Outgoing Call Rule, please refer to the user
manual: CH3.1.6.1 Outgoing Call Rule.
Absolute Timeout: Specific the timeout value for the outgoing calls. Please also go
to Outgoing Call Rule page to enable the Route Timeout function.
BLF: Enable BLF function for extensions.
Forward CallerID: By default, the “from header of SIP invite” will contain the caller’s
line number when forward function is activated. But this may make some errors
occurred for some SIP Trunk services. So we add this function in the “Extension
Setting” page, to let user modify the line number of SIP Invite’ s from header, from
calling party’s number to the called party’s number.
Comment: You can input a 10 bytes note for each extension here.
Mail Box: User can select to disable or enable mail box function. If this function is
enabled, user could input e-mail address for the Extension. When having voice mail of
incoming call, system will send this voice mail to the specified e-mail address. You can
also login the mail box system by dialing to *98, if you are using an ePBX-100A-128.
E-Mail Address: This field will appear when you enable Mail Box function and you can
input the E-Mail Address here for voice mail to E-mail.
Save VM to CF: Optional to not save voice mail to CF card.
VM Login Password: User can login voice mail system by dialing to *98, then input
the mailbox number and password for voice mail. User can define the Voice Mail box
login password here. Another way to login the voice mail system is dial to
*98+extension number. For example, dial to *98101 can login EXT101’s voice mail box,
and caller can just input password to access voice mail.
Note:
•Please remember set the SMTP in the page of Management ÆSMTP Setting
to activate the Voice Mail to E-mail.

15
•If the ePBX-100A-128 got a new message, it will send the message to the
user by email immediately. If you just hope the ePBX-100A to save voice
mail to it and not send the email. You just need to input “x” to E-Mail
Address.
Voice Mail Count: View the exact count of New Messages and Old Messages.
Delete MailBox Content: User can delete all of the voice mails and personal greeting
by mark the “Delete MailBox Content” and then press Apply.
Press Apply to save configuration, or press Cancel to quit configuration.
2.5.3 Trunk Configuration
User has to set Trunk account for Trunk (FXO device, e.g. WG3804A) to register to
ePBX-100A-128 or set some necessary configuration for SIP trunk (For more application,
please go to…….). Enter Configuration ÆTrunk to configure Trunk data.
User can press Modify to add new Trunk or modify configured Trunk data. Press
Delete will delete the specified Trunk.
After press Modify can input detail setting for Trunk.

16
Trunk Number: Assign the number of Trunk. This number is also the register name for
Trunk device.
Note:
•The Trunk Number can also be a “Trunk ID”. In the Routing Table page, you
should define the destination of prefix route. When you define the prefix route,
you should set the Trunk ID (Trunk Number) in the Trunk page first; then you
could input the correct Trunk ID in the Destination field.
Password: Assign the register password for device to register on ePBX-100A-128.
Host: Setting the Host to Dynamic will require the trunk to register the ePBX-100A-128
so that the ePBX-100A-128 know how to reach the trunk. You can also set the Host to
an IP address or FQDN if you set the Host to [Pre-define]. There will be a field called
[Address] appeared when you choose Host to [Pre-define]. This limits only where you
place calls to, as the user is allowed to place calls from anywhere.
DialPlan: Define the dialing plan for Trunk. It specifies the location of the instruction
used to control what the phone is allowed to do, and what to do with incoming calls for
this Trunk. In this field, you can Choose 6 dial level for Extension, including [from-pstn],
[ext-only], [ext+R1], [ext+R12], [ext+R123], [ext+allroutes]. You can define an
“Outgoing call” record, to a certain route level, as R1, R2…, etc. [from-pstn] is used for
Trunk only. [ext-only] means this subscriber can only call to Extension. [ext+R1] means
the subscriber with such DialPlan can call to Extension and Route Level with R1.
[ext+R12] means the subscriber with such DialPlan can call to Extension and Route
Level with R1 and R2. [ext+R123] means the subscriber with such DialPlan can call to
Extension and Route Level with R1, R2 and R3. [ext+allroutes] means the subscriber

17
with such DialPlan can call to Extension and Route Level with R1, R2, R3 and R4.
Note:
•For more information about Route Level, please refer to the user manual: 3.1.6.1
Outgoing Call Rule.
Keypad: User can select Keypad type to be RFC2833, In-band, or SIP-Info and Auto.
You can choose Auto to auto select the Keypad type. Choose RFC2833, Inband or
SIP-Info here will force the Extension use RFC2833, Inband or SIP-Info only and the
setting should be also match the Keypad setting of Trunk device.
NAT Traversal: If the Trunk device is behind a device performing NAT, such as firewall
or router, and need to register to ePBX-100A-128 on public network, then user has to
enable this function. Enable NAT Traversal to force ePBX-100A-128 to ignore the
contact information for the Trunk and use the address from which the packets are
being received.
RTP Mode: User can choose for two type of RTP mode, one is Routed Mode another
is Direct Mode. The voice media will be routed “Peer-to-Peer” if two clients are both
setting to Direct Mode. This way will improve the voice quality and reduce the
performance wastage of the ePBX-100A-128.
Note:
•If one peer set to Direct Mode but another peer set to Routed Mode, the result will
become to Routed Mode.
•Voice media will still go through the ePBX-100A-128 if the ePBX-100A-128 needs
to detect DTMF.
•If you enable the NAT Traversal function for Extension, the RTP mode will change
to Routed Mode directly; this way will avoid the “one-way voice” or “no voice
issue” of VoIP.
•If the both peers are under different subnet, or one peer is under Public IP but
another one is under Private IP, we strongly suggest you to set the RTP mode
to Routed Mode to avoid some unexpected voice problems.
Port: You can use this to define the SIP signal port if you want to listen on a
nonstandard SIP signal port.
External Server Address: This field will allow you to set the domain in the SIP From
URI. Setting this will avoid some unexpected issue if the service provider needs this for
authentication.
Maximum Channels: This will limit the maximum channels for this Trunk. For example,
you set 2 into this field; only 2 outgoing calls could go via this Trunk. Default is no limit.
Outbound Caller ID: Some service provider will require the correct registered caller ID
if it got an incoming call. Default the ePBX-100A-128 will send the Extension’s caller ID
to this Trunk, if you set empty here.

18
Note:
•Normally, SIP From URI will contain the Extension’s calling ID and
ePBX-100A-128’s IP address, but some ITSP may reject this call due to some
security issue. You can modify the Calling ID and IP/ Domain in the fields of
[External Server Address] and [Outbound Caller ID] when the call is going via the
ePBX-100A-128 to the Destination (Trunk) to avoid such security issue.
•If you set a Welltech FXO gateway as the Trunk, you can just use the default
Trunk 888 and 889 as the FXO’s register number.
•For the FXO gateway, you may just only configure Trunk Number, Password,
Host, DialPlan, Keypad, NAT Traversal and RTP Mode.
•If you set the ITSP as the Trunk, you may need to set the following configure: Port,
External Server Address and Outbound Caller ID.
•For more information, please refer to the user manual
CH5.1Appendix-Application between Welltech CPE device and
ePBX-100A-128
Comment: You can input a 10 byte note for each Trunk here.
Hot-Key Tran: Enable this feature will permits the calling party or called party to
transfer a call by pressing the *0 (For Blind Transfer) or *9 (For consultant Transfer)
key if the call is Between Extension and Trunk. Default is disabled.
Note:
•If you enable this feature in Trunk page, we suggest you also enable Hot-Key
Tran of IP PBX page.
•Please note that if this option is used, the RTP Mode will always be Routed Mode,
as ePBX-100A-128 needs to monitor the call to detect when the caller presses
the *0 or *9 key.
Music RBT: Provides music to the calling party until the call is answered
Press Apply to save configuration, or press Cancel to quit configuration.
