1. Product Description
This guide describes basic use of the Sipura Technology SPA phone adapter – an intelligent low-
density Voice over IP (VoIP) gateway. The SPA enables carrier class residential and business IP
Telephony services delivered over broadband or high-speed Internet connections. By intelligent, we
mean the SPA maintains the states of all the calls it terminates. It is capable of making proper
decisions in reaction to user input events (such as on/off hook or hook flash) with little or no
involvement by a ‘middle-man’ server or media gateway controller.
Examples of proper reactions are: playing dial tone, collecting DTMF digits, comparing them against a
dial plan and terminating a call. With intelligent endpoints at the edges of a network, performing the
bulk of the call processing duties, the deployment of a large network with thousands of subscribers
can scale quickly without the introduction of complicated, expensive servers. As described later in
this section, the Session Initiation Protocol (SIP) is a good choice of call signaling protocol for the
implementation of such a device in this type of network.
1.1.SPA Hardware Overview
The SPA has one of the smallest form factors on the market. It can be installed in minutes as a table-
top or wall mount CPE device. The images below show the SPA-2000. The SPA-1000 and SPA-
3000 are similar to size and shape – the only difference being the color of the adapter.
Figures Figure 1, Figure 2, Figure 3 and Figure 4 show the front, rear, left side and right side of the
SPA-2000, respectively.

The SPA has the following interfaces for networking, power and visual status indication:
1. Two (2) RJ-11 Type Analog Telephone Jack Interfaces (Figure 4, above):
These interfaces accept standard RJ-11 telephone connectors. An Analog touchtone telephone or
fax machine may be connected to either interface. If the service supports only one incoming line, the
analog telephone or fax machine should be connected to port one (1) of the SPA. Port one (1) is the
outermost telephone port on the SPA and is labeled “Phone 1.”
The SPA-3000 has an RJ-11 interface labeled “Line” which can be used to connect the adapter to a
PSTN analog telephone circuit.
2. One LED for Unit Status (Figure 4, above):
3. One Ethernet 10baseT RJ-45 Jack Interface (
Figure 2, above):
This interface accepts a standard or crossover Ethernet cable with standard RJ-45 connector. For
optimum performance, Sipura Technology recommends that a Category 5 cable or greater be used in
conjunction with the SPA.
4. One LED for Data Link and Activity (
Figure 2, above):
5. One 5 Volt Power Adapter Interface (
Figure 2, above)
This interface accepts the SPA power adapter that came with the unit. Sipura Technology does not
support the use of any other power adapters other then the power adapter that was shipped with the
SPA unit.

3. Software Configuration
3.1.1.1. Firmware Upgrade
Firmware Upgrade via PC Utility Program:
From time to time, Sipura Technology will make available a PC executable file that will facilitate the
upgrade of a SPA. In order to upgrade a device via this method, the end user must have
administrative permission (via password protected log-in) to perform this upgrade.
Once the user has obtained the proper firmware upgrade executable, the user simply runs the
program from a file location on their local PC. The PC program walks the user through the upgrade
process via a graphical user interface. Generally, the entire upgrade process should take no more
than five minutes to complete.
Please note: Some end-users who have obtained their SPA directly from a service provider will never
need to manually upgrade their device. Via the remote upgrade process, Sipura Technology provides
capability for the SPA to be maintained from a remote location (e.g. a service provider network
server), using the Internet connection of the end-user as the conduit through which profile updates
and firmware upgrades are performed.
3.2.IVR Interface
Administrators and/or users can check (read) and set (write) basic network configuration settings via
a touchtone telephone connected to one of the RJ-11 phone ports of the SPA.
Please Note:
Service Providers offering service using the SPA may restrict, protect or turn off certain aspects of the
unit’s IVR and web configuration capabilities.
The Interactive Voice Response (IVR) capabilities of the SPA are designed to give the administrator
and/or user basic read/write capabilities such that the unit can attain basic IP network connectivity
and the more advanced browser-based configuration menu may be accessed.
1. The SPA IVR uses the following conventions: By factory default there is no password and no
password authentication is prompted for all the IVR settings. If administrator password is set,
password authentication will be prompted for certain IVR settings. See 3.4.2 for detailed information
about administrator password.
To input the password using the phone keypad, the following translation convention applies:
oTo input: A, B, C, a, b, c -- press ‘2’
oTo input: D, E, F, d, e, f -- press ‘3’
oTo input: G, H, I, g, h, i -- press ‘4’
oTo input: J, K, L, j, k, l -- press ‘5’
oTo input: M, N, O, m, n, o -- press ‘6’
oTo input: P, Q, R, S, p, q, r, s -- press ‘7’
oTo input: T, U, V, t, u, v -- press ‘8’
oTo input: W, X, Y, Z, w, x, y, z -- press ‘9’
oTo input all other characters in the administrator password, press ‘0’

© 2003 - 2004 Sipura Technology, Inc Proprietary (See Copyright Notice on Page 2)

Note: This translation convention only applies to the password input.
For example: to input password “test#@1234” by phone keypad, you need to press the following
sequence of digits: 8378001234.
2. After entering a value, press the #(pound) key to indicate end of input.
oTo Save value, press ‘1’
oTo Review the value, press ‘2’
oTo Re-enter the value, press ‘3’
oTo Cancel the value entry and return to the main configuration menu, press ‘*’ (star)
Notes:
oThe final ‘#’ key won’t be counted into value.
oSaved settings will take effect when the telephone is hung-up and if necessary, the SPA will
automatically reboot.
3. After one minute of inactivity, the unit times out. The user will need to re-enter the configuration
menu from the beginning by pressing * * * *.
4. If, while entering a value (like an IP address) and you decide to exit without entering any changes,
you may do so by pressing the *(star) key twice within a half second window of time. Otherwise,
the entry of the *(star) key will be treated as a dot (decimal point).

3.3.Web Interface
The SPA provides a built-in web server. Configuration and administration can be performed through
this convenient web interface.
3.3.1. Web Interface Conventions
The SPA uses the following conventions with the web administration capabilities:
oThe SPA web administration supports two privilege levels: Administrator and User. To use
the User privilege, simply point a web browser at the IP address of the SPA; to use the
administrator privilege, use URL http://IP_Address_Of_SPA/admin/. See 3.3.2 for more
information about administration privileges.
oVersion 1.0 of the SPA supports Internet Explorer 5.5 and above and Netscape 7.0 and
above.
oThe web configuration pages can be password protected. See 3.3.2 for more information
about password protect.
oThe user name of web Administrator is : admin
oThe user name of web User is : user

© 2003 - 2004 Sipura Technology, Inc Proprietary (See Copyright Notice on Page 2)
12
oNote: The user names for both administrator and User are fixed and cannot be changed.
oAfter making changes to SPA configuration parameters, pressing “Submit All Changes”
button will apply all the changes and if necessary, automatically reboot the device. Multiple
changes may be made on multiple page tabs of the web interface at the same time. Pressing
“Submit All Changes” will apply all the modifications.
Important Note: switching between page tabs won’t apply the changes to SPA, The only way
to apply the changes is to press the “Submit All Changes” button.
oIf the “Undo All Changes” button is clicked, any modifications to profile parameters on any and
all pages will be reset back to their original values before modification.
NOTE: Pressing the “Undo All Changes” has no effect on the SPA; it will only reset the
values on the web page.
3.3.2. Administration Privileges
The SPA supports two levels of administration privileges: Administrator and User, both privileges can
be password protected. Important note: by factory default, there are no passwords assigned for both
Administrator and User.
The Administrator has the privilege to modify all the web profile parameters and can also modify the
passwords of both Administrator and User. A User only has the privilege to access part of the web
profile parameters; the parameter group that User can access is specified by the Administrator, which
can only be done through provisioning.
To access the Administrator level privilege, use URL: http://IP_Address_Of_SPA/admin/. If the
password has been set for Administrator, the browser will prompt for authentication. The username
for Administrator is “admin” and cannot be changed.
To access the User level privilege, use URL: http://IP_Address_Of_SPA/. If the password has been
set for User, the browser will prompt for User authentication. The username for User is “user” and
cannot be changed.
When browsing Administrator pages, one can switch to User privileges by click the link “User Login”.
(Note: if User password was set, the browser will prompt for User authentication when you click “User
Login” link). On the other side, from the User pages you can switch to Administrator privilege by
clicking the link “Admin Login.” Authentication is needed if Administrator password has been set.
Warning: Switching between the User and Administrator will discard the uncommitted changes that
have already been made on the web pages.
3.3.3. Basic and Advanced Views
The web configuration interface provides a Basic and an Advanced view from which the various
configuration parameters can be accessed. The SPA Provisioning tab is only visible from the
Advanced Administrator view of the web interface.
Warning: Switching between the basic and advanced view will discard the uncommitted changes that
have already been made on the web pages.
3.3.3.1. Resync URL
Through Resync URL you can force the SPA to do a resync to a profile specified in the URL.
Note: The SPA will resync only when it is idle.
The syntax of Resync URL is:

© 2003 - 2004 Sipura Technology, Inc Proprietary (See Copyright Notice on Page 2)
13
http://<spa-ip-addr>/resync?[[protocol://][server-name[:port]]/profile-pathname]
If no parameter follows “/resync?”, the profile rule setting in provisioning is used. See Error!
Reference source not found. for detailed information about profile rule in provisioning
If no protocol is specified, TFTP protocol is assumed. Note: Only TFTP is supported in the current
release.
If no server-name is specified, the host that requests the URL is used as server-name.
If no port specified, default port of the protocol is used – 69 for TFTP.
The profile-path is the path to the new profile to resync with.
For example: http://192.168.2.217/upgrade?tftp://192.168.2.251/spaconf.scf

and reception 16482
RTP Packet Size Packet size in sec. Valid values must be
multiple of 0.01s. Range: 0.01 – 0.16 0.02
RTCP Tx Interval4Controls the interval (sec) to send out RTCP
sender report on an active connection.
Range: 0 – 255 (s)
0
Notes:
1. Reorder or Busy Tone will be played by default for all unsuccessful response status code
2. <RTP Port Min> and <RTP Port Max> should define a range that contains at least 4 even number
ports, such as 100 – 106
3. If inbound SIP requests contain compact headers, SPA will reuse the same compact headers
when generating the response regardless the settings of the <Use Compact Header> parameter.
If inbound SIP requests contain normal headers, SPA will substitute those headers with compact
headers (if defined by RFC 261) if <Use Compact Header> parameter is set to “yes.”
4. During an active connection, the SPA can be programmed to send out compound RTCP packet
on the connection. Each compound RTP packet except the last one contains a SR (Sender
Report) and a SDES.(Source Description). The last RTCP packet contains an additional BYE
packet. Each SR except the last one contains exactly 1 RR (Receiver Report); the last SR carries
no RR. The SDES contains CNAME, NAME, and TOOL identifiers. The CNAME is set to <User
ID>@<Proxy>, NAME is set to <Display Name> (or “Anonymous” if user blocks caller ID), and
TOOL is set to the Verdor/Hardware-platform-software-version (such as Sipura/SPA2000-
1.0.31(b)). The NTP timestamp used in the SR is a snapshot of the SPA’s local time, not the time
reported by an NTP server. If the SPA receives a RR from the peer, it will attempt to compute the
round trip delay and show it as the <Call Round Trip Delay> value (ms) in the Info section of SPA
web page.
3.4.4.1. Dynamic Payload Types
Parameter Name Description Default
NSE Dynamic Payload1,2 NSE dynamic payload type 100

18
2. The configured dynamic payloads are used for outbound calls only where the SPA presents the
SDP offer. For inbound calls with a SDP offer, SPA will follow the caller’s dynamic payload type
assignments
3.4.4.2. SDP Audio Codec Names
Parameter Name Description Default
NSE Codec Name NSE Codec name used in SDP NSE
AVT Codec Name AVT Codec name used in SDP telephone-event
G711a Codec Name G711a Codec name used in SDP PCMA
G711u Codec Name G711u Codec name used in SDP PCMU
G726r16 Codec Name G726-16 Codec name used in SDP G726-16
G726r24 Codec Name G726-24 Codec name used in SDP G726-24
G726r32 Codec Name G726-32 Codec name used in SDP G726-32
G726r40 Codec Name G726-40 Codec name used in SDP G726-40
G729a Codec Name G729a Codec name used in SDP G729a
G729b Codec Name G729b Codec name used in SDP G729ab
G723 Codec Name G723 Codec name used in SDP G723
Notes:
1. SPA uses the configured codec names in its outbound SDP
2. SPA ignores the codec names in incoming SDP for standard payload types (0 – 95).
3. For dynamic payload types, SPA identifies the codec by the configured codec names. Comparison
is case-insensitive.
3.4.4.3. NAT Support
Parameter Name Description Default
Handle_VIA_received If set to “yes”, the SPA will process the “received”
parameter in the VIA header inserted by the server
in a response to any one of its request. Else the
parameter is ignored.
No
Handle_VIA_rport If set to “yes”, the SPA will process the “rport”
parameter in the VIA header inserted by the server
in a response to any one of its request. Else the
parameter is ignored.
No
Insert VIA received Insert received parameter in VIA header in SIP
responses if received from IP and VIA sent-by IP
differ
No
Insert VIA rport Insert rport parameter in VIA header in SIP
responses if received-from port and VIA sent-by
port differ
No
Substitute VIA addr Use nat-mapped IP:port values in VIA header No
Send Resp To Src Port Send response to the request source port instead of
the VIA sent-by port No
STUN Server STUN server to contact for NAT mapping discovery
STUN Enable Enable the use of STUN to discover NAT mapping No
STUN Test Enable If enabled with <STUN Enable> = “yes” and a valid
<STUN Server>, the SPA will perform a NAT type
discovery operation when first power on by
contacting the configured STUN server. The result
of the discovery will be reported in a Warning
No

header in all subsequent REGISTER requests –
“Warning: 399 spa <stun type>”, where <stun type>
is one of the following:
"Unknown NAT Type",
"STUN Server Not Reachable",
"STUN Server Not Responding",
"Open Internet Detected",
"Symmetric Firewall Detected",
"Full Cone NAT Detected",
"Restricted Cone NAT Detected",
"Symmetric NAT Detected";
If the SPA detects Symmetric Nat or Symmetric
Firewall, Nat Mapping will be disabled (that is, no
substitution of IP address and port with external IP
address an nat-mapped port)
Ext IP External IP address to substitute for the actual IP
address of the unit in all outgoing SIP messages. If
“0.0.0.0” is specified, no IP address substitution is
performed.
0.0.0.0
Ext RTP Port Min External port mapping of <RTP Port Min>. If this
value is non-zero, the RTP port number in all
outgoing SIP messages is substituted by the
corresponding port value in the external RTP port
range.
0
NAT Keep Alive Intvl Interval between sending NAT-mapping keep alive
message in sec 15
Notes:
3.4.5. Line 1 and Line 2 Parameters
Per line parameter tags must be appended with [1] or [2] (corresponding to lines 1 or 2) in the
configuration profile. It is omitted below for readability.
3.4.5.1. User Account Information
Parameter Name Description Default
Line Enable Enable this line for service Yes
MOH Server2The User ID or URL of the auto-answering SAS to
contact for MOH services. Examples: 5000,
[e-mail], 66.12.123.15:5061.
Note: When only a user-id is given, the current
proxy or outbound proxy will be contacted as in the
making of a regular outbound call. MOH is disabled
if this parameter is not specified (empty).
Empty
SIP Port SIP message listening port and transmission port 5060
Ext SIP Port External port to substitute for the actual SIP port of
the unit in all outgoing SIP messages. If “0” is
specified, no SIP port substitution is performed.
0

SAS Enable3Enables the FXS Line to act as a Streaming Audio
Source (SAS). If enabled, the line cannot be used
for making outgoing calls. Instead, it auto-answers
incoming calls and streams audio RTP packets to
the calling party.
No
SAS DLG Refresh
Intvl3If non-zero, this is the interval at which SAS sends
out session refresh (SIP re-INVITE) messages to
detect if connection to the caller is still up. If the
caller does not respond to refresh message, SPA
will terminate this call with a SIP BYE message.
The default = 0 (Session refresh disabled)
Range = 0-255 (s)
0
SAS Inbound RTP
Sink3The purpose of this parameter is to work around
devices that do not play inbound RTP if the SAS
line declares itself as a “sendonly” device and tells
the client not to stream out audio. This parameter is
a FQDN or IP address of a RTP sink to be used by
the SPA SAS line in the SDP of its 200 response to
inbound INVITE from a client. It will appear in the c
= line and the port number and, if specified, in the
m = line of the SDP. If this value is not specified or
equal to 0, then c = 0.0.0.0 and a=sendonly will be
used in the SDP to tell the SAS client to not to send
any RTP to this SAS line. If a non-zero value is
specified, then a=sendrecv and the SAS client will
stream audio to the given address. Special case: If
the value is $IP, then the SAS line’s own IP
address is used in the c = line and a=sendrecv. In
that case the SAS client will stream RTP packets to
the SAS line. The default value is [empty].
NAT Mapping Enable Enable the use of externally mapped of IP address
and SIP/RTP ports in SIP messages. The mapping
may be discovered by any of the supported
methods.
No
NAT Keep Alive
Enable If set to “yes”, the configured <NAT Keep Alive Msg> is sent periodically every <NAT Keep Alive
Intvl> seconds.
No
NAT Keep Alive Msg Contents of the keep-alive message to be sent to a
given destination periodically to maintain the
current NAT-mapping. It could be an empty string.
If value is $NOTIFY, a NOTIFY message is sent as
keep alive. If value is $REGISTER, a REGISTER
message w/o Contact is sent.
$NOTIFY
NAT Keep Alive Dest Destination to send NAT keep alive messages to. If
value is $PROXY, it will be sent to the current
proxy or outbound proxy
$PROXY
SIP Debug Option None, 1-line, full, exclude OPTIONS, exclude
REGISTER, exclude NOTIFY, … none
Network Jitter Level 4 settings are available: very high, high, medium,
low. This parameter affects how jitter buffer size is
adjusted in the SPA. Jitter buffer size is adjusted
dynamically. The minimum jitter buffer size is 30
ms or (10 ms + current RTP frame size), which
ever is larger, for all jitter level settings. But the
High
