Configuring the Cisco SPA8800 IP Telephony Gateway in an Asterisk Environment
Introduction
®
The Cisco SPA8800 IP Telephony Gateway provides four RJ-11 FXS and four FXO ports, a
10/100BASE-T RJ-45 Ethernet interface to connect to either a router or multilayer switch, and an
auxiliary port for local administration. It also provides a single multiport RJ-21 50-pin connector.
®
The SPA8800 can in only a matter of minutes, be easily be configured as an Asterisk FXO
gateway.
Calls originating from the public switched telephone network (PSTN) can be terminated by the
SPA8800's FXO ports and routed to analog or IP phones based on an Asterisk server's
configuration. Analog phones connected to the SPA8800 can make low-cost VoIP calls via an
Internet Telephony Service Provider (ITSP) or can make calls via the PSTN.
Many interesting call routing options are possible using Asterisk to control the SPA8800 gateway.
Asterisk can be configured to trunk the SPA8800's four FXO ports together into a trunk group. A
trunk group allows the PSTN lines connected to the FXO ports to be over-subscribed and shared
among all configured analog and IP phones, effectively lowering telephony costs by not requiring a
dedicated line per phone. For example, you can have 4 connected PSTN lines and share them with
th
any number of phones. When all 4 lines are busy, the 5 user will hear a congestion tone.
Additionally, the SPA8800's FXS ports can be used in other ways, including connecting analog
phones, door phones, and fax machines.
The SPA8800 supports fax with G.711 pass-through or real-time fax over IP via T.38 fax relay and
also supports the G.711 A-law, G.711 µ-law, G.726, G.729A, G.723.1 voice codecs.
In the event that you only need FXS ports and do not need any FXO ports, consider using the
Cisco SPA8000 8-Port IP Telephony Gateway. The SPA8000 configuration is very similar to the
SPA8800.
Audience
This application note is targeted at anyone who needs an FXO gateway for their Asterisk server. It
is expected that readers of this document are familiar with the administration tasks involved with
configuring VoIP in an Asterisk environment.
Scope
This scope of this document is limited to configuring the SPA8800 in an Asterisk environment and
does not address the following topics:
• Installing an Asterisk server
• Advanced Asterisk configuration
• SPA8800 localization
• Security
Refer to the Related Documents for additional configuration and background information.

Overview
Configuring the SPA8800 is a relatively trivial task and is similar to configuring any of the Sipura /
Linksys / Cisco ATA and SPA9000 Voice System devices. Troubleshooting configuration problems
due to incorrectly typed information in configuration fields requires advanced network and Asterisk
troubleshooting skills. This application note walks you through configuring a SPA8800 and also
provides sample traces that may be of use to you when you are troubleshooting your SPA8800 in
an Asterisk environment.
By the end of this document, an Asterisk phone user, analog or IP, will be able to pick up a phone
and dial out via the PSTN or ITSP, depending on the steering digit they use.

Configuring the Cisco SPA8800 IP Telephony Gateway in an Asterisk Environment
Requirements
You need the following equipment and services:
• A functional Asterisk server
• A functional LAN with network connectivity to the Internet and an optional Internet Telephony
Service Provider (ITSP)
• A SPA8800
• One to four analog phones
• Optional IP phones such as the SPA525G, SPA9x2, SPA9x1, or WIP310 (wireless) IP phones
Configuring Asterisk for a SPA8800
Before you configure your Asterisk server for the SPA8000, you need to gather some basic
information:
1.
Static IP address for the SPA8800. By default, this device is a DHCP client, but will be of no
use to you if it is assigned a new dynamic IP address periodically. In this document, I use
192.168.2.237/24
2.
Gateway / Default router, DNS, and NTP server IP addresses
3.
Extension numbers for up to four analog phones to be connected to the SPA8800's PHONE
FXS ports 1-4. In this document, I use 101, 102, 103, and 104.
4.
Decide how many PSTN lines will be connected to the SPA8800's LINE FXO ports 1-4. In this
document, I use two PSTN lines connected to FXO LINE ports 2 and 3 [UDP 5161 and 5261
respectively]
5.
Decide what steering digits to use. In this document, I use 8 for PSTN and 9 for ITSP
6.
Decide what phone or phones to route inbound PSTN and ITSP calls to. In this document, I will
route all inbound calls to the analog phone associated with extension 101.
7.
Decide what to name the SPA8800 context group in the extensions.conf file. In this document,
I use the [fxsgroup] context.

Configuring FXO Line Dial Plans for inbound PSTN call
Routing
In this section, you will configure FXO port dial plans. These dial plans affect inbound PSTN call
routing and work in conjunction with definitions made in the /etc/asterisk/sip.conf and
/etc/asterisk/extensions.conf files.
The [general] section of sip.conf contains the register directive which instructs the SIP proxy on
where (101) to send inbound calls:
[general]
register => 3615551212@sip.broadvoice.com:mypassword:3615551212@sip.broadvoice.com/101
The [pstn2] and [pstn3] contexts of the extensions.conf file describes how inbound calls must be
routed:
[pstn2]
exten => 101,1,Dial(SIP/101,60,rt)
[pstn3]
exten => 101,1,Dial(SIP/201,60,rt

Edit any dial plan to route inbound calls from the PSTN line connected to this FXO line. In
this example, Dial Plan 8 is edited with: (<:101@192.168.2.20>S0) where:
All inbound calls will be routed to extension 101 of the Asterisk server [192.168.2.20].

The entire configuration process is complete once the SPA8800 has rebooted.
Testing the Phone System
Test the phone system as follows for appropriate behavior:
1.
Test internal calls:
a.
Verify that analog phones can call each other internally. For example
call from 101 to 102.
b.
Optional: Verify that analog phones can call IP phones internally. For
example, call from 101 to 200 [if configured]
2.
Test inbound calls:
a.
From the PSTN, call a phone line attached to the SPA8800's FXO line.
Verify that the appropriate phone rings, analog phone 101 in this
document's example.
b.
From the PSTN, call a DID associated with the Asterisk server.
Verify that the appropriate phone rings, analog phone 101 in this
document's example.
3.
Test outbound calls:
a.
From an analog phone, make an outbound call using the PSTN by using
the appropriate steering digit, 8 in this document's example.
b.
From an analog phone, make another simultaneous outbound call using
the PSTN by using the appropriate steering digit, 8 in this document's
example. Verify that both calls succeed, using both configured outbound
PSTN lines.
c.
From an analog phone, make an outbound call using the ITSP by using
the appropriate steering digit, 9 in this document's example.

T.38 Faxing
The SPA8800 supports fax with G.711 pass-through or real-time fax over IP via T.38 fax relay.
The only change from default setting for fax pass-through is to change from the default named
signaling event (NSE) to ReINVITE:
Web-ui > Voice tab > Line N tab > Audio Configuration > FAX Passthru Method: ReINVITE
Optionally, you can change the FAX Line Toggle code from the default of #99. Predialing #99 as a
prefix forces the call to be a fax call. This will case the INVITE to indicate T.38 in the SDP without
relying on a reINVITE to switch to T.38. The default can be changed from #99 with the
web-ui > Voice tab > Regional tab > Vertical Service Activation Codes > FAX Line Toggle Code:

Codecs
The SPA8800 supports the G.711 A-law, G.711 µ-law, G.726, G.729A, G.723.1 voice codecs.
Use the Asterisk CLI to determine the codecs in use during a call:

Troubleshooting
Verify that the SPA8800's analog phones attached to the PHONE ports are registered.
1.
Direct your browser to the SPA8800's web user interface (web-ui)
http://<IP_address_of_SPA8800>/admin/advanced
2.
Voice tab > Info tab > Phone N Status > Registration State
3.
Voice tab > Info tab > PSTN Line N Status > Line Voltage
Verify that line voltage is present. A voltage of 0 indicates that the PSTN line is not properly
connected.
Registration state of Failed is normal for a properly configured system.

Troubleshooting Rejected Because Extension not Found
Failing Inbound from ITSP
*CLI>
[May 20 10:06:45] NOTICE[16549]: chan_sip.c:13865 handle_request_invite: Call from
'3615551212' to extension '3615551212' rejected because extension not found.
The above message can be a result of incorrect inbound call routing in the extensions.conf file
when using Broadvoice.com as an ITSP. Instead of the following in the [itsp1] context:
exten => 101,1,Dial(SIP/101,25,Ttr)
Change to:
exten => 3615551212,1,Dial(SIP/101,25,Ttr)
Failing Inbound from PSTN
[Jun
3 17:34:37] NOTICE[31613]: chan_sip.c:14035 handle_request_invite: Call from
'pstn3' to extension '101' rejected because extension not found.
This indicates that an inbound call to the port named pstn3, is being routed to extension 101.
Looking through extensions.conf and sip.conf, all is normal, yet the inbound call does not ring on
extension 101. The problem in this scenario is that the SPA8800 Line N's dialplan has been
incorrectly configured and is routing the call to extension 101 while extensions.conf is routing the
call elsewhere. Correcting the dialplan on the SPA8800 and then saving the configuration solved
the problem.

SPA8800 Debug and syslog
The SPA8800 supports writing debug and syslog messages to syslog servers. One server can be
used, or separate servers can be used to receive messages. Four levels of verbosity are
supported, 0 for no messages, 1 for terse, through 3 for verbose message output:
Following is an example of syslog information produced at Debug Level 3 [numbers changed]. This
example shows when the phone goes off hook, digits dialed, calling information, a report that an
unlisted codec is being requested, and when the phone goes back on hook:

Sample Traces
Sometimes, the best way to troubleshoot Asterisk and SPA8800 interaction issues is to capture a
trace and compare it against a similar transaction. Following are three traces showing in order:
1.
A successful registration between the SPA8800 and the Asterisk server and a successful
registration between the Asterisk server and the broadvoice.com SIP proxy.
[IP addresses have been changed]
2.
An inbound call from the PSTN routed to extension 101
3.
An inbound call from the ITSP routed to extension 101
4.
An outbound call from extension 101 via the PSTN
5.
An outbound call from extension 101 via the ITSP
