[Freeswitch-users] Simple SPA8800 FXO connection to FreeSwitch

[Robin Gilks]

Greetings

I'm a noob with FS (and VoIP generally!!) and am really struggling
with getting 2 way comms between a PABX and a soft-phone using FS and
an SPA8800.

Calls from the PABX are OK, the FXO ports have registered with FS and
when I dial the FXO extension I get the dial tone, dial the number for
the soft-phone and it all works fine.

The problem is connections *TO* the PABX. The SPA8800 AFAIK has a
separate SIP port for each of its FXO ports. My understanding of how
it should work is as follows:

I have to have 4 gateways defined in a file in the
sip-profiles/externals directory, each with a different "sip-port"
line. I'm testing with 2 to start with:

# cat cicsco_fxo.xml
<include>
  <gateway name="fxoline3">
    <param name="username" value="none"/>
    <param name="password" value="none"/>
    <param name="realm" value="172.27.1.20"/>
    <param name="sip-port" value="5260"/>
    <param name="register" value="false"/>
  </gateway>
  <gateway name="fxoline4">
    <param name="username" value="none"/>
    <param name="password" value="none"/>
    <param name="realm" value="172.27.1.20"/>
    <param name="sip-port" value="5360"/>
    <param name="register" value="false"/>
  </gateway>

I have to use mod_distributor to select one of the gateways that
define the SIP ports. Thats is configured in the autoload_configs
directory.

# cat distributor.conf.xml
<configuration name="distributor.conf" description="Distributor Configuration">
  <lists>
    <list name="cisco_fxo" total-weight="2">
      <node name="fxoline3" weight="1"/>
      <node name="fxoline4" weight="1"/>
    </list>
  </lists>
</configuration>

Finally, I use a dialplan to access this distribution of gateways when
a 4 digit number starting with 8 is dialed from the soft-phone.

# cat 33_ciscofox.xml
<include>
  <extension name="pabx">
    <condition field="destination_number" expression="^(8\d{3})$">
      <action application="bridge"
data="sofia/gateway/${distributor(cisco_fxo)}/$1"/>
    </condition>
 </extension>
</include>

Result expected - it all works.
Result I get is:

So what is invalid about the gateway?
