[Freeswitch-users] problems with Faktortel (AU) and multiple D ID's and extensions

Tue Apr 7 17:13:13 PDT 2009

Hi David,
Have seen a similar issue reported on whirlpool recently with another provider, essentially if the ITSP does not forward the To: header with the correct terminating DID you will not be able to determine the extention to route the call to.  Am I correct in saying you only have one Faktortel account with 2 DIDs attached? 
Regards,
Jim

I have been trying to setup 2 DID's to route to 2 extensions but 
whenever I try it, the second configured DID always routes to the first 
extension.

In my public.xml I have the following:

<include>
  <context name="public">

    <extension name="DID 1">
        <condition field="destination_number" expression="^(0746029000)$">
            <action application="transfer" data="1000 XML default"/>
        </condition>
    </extension>

    <extension name="DID 2">
        <condition field="destination_number" expression="^(0746029002)$">
            <action application="transfer" data="1001 XML default"/>
        </condition>
    </extension>

.... rest of file continues here ...

While in my default.xml I have this:

<include>
  <context name="default">

    <extension name="David">
        <condition field="destination_number" 
expression="^(0746029000)$" continue="on-true">
            <action application="set" data="dialed_ext=$1" />
        </condition>
        <condition field="destination_number" 
expression="^${caller_id_number}$">
            <action application="set" 
data="voicemail_authorized=${sip_authorized}"/>
            <action application="answer"/>
            <action application="sleep" data="1000"/>
            <action application="voicemail" data="check default

            <anti-action application="ring_ready"/>

    </extension>

    <extension name="Jake">

        </condition>
        <condition field="destination_number"

            <anti-action application="voicemail" data="default

        </condition>
    </extension>

    <extension name="outgoing - voicepulse">

            <action application="set"

            <action application="bridge" 
data="sofia/gateway/voicepulse/$1"/>
        </condition>
    </extension>

I got my new friend swk to try and diagnose the problem and using ngrep 
he found with ngrep that the incoming call to the second extension 
looked like this:

U 203.161.130.133:5060 -> 10.0.0.12:5080
  INVITE sip:gw+voicepulse at 10.0.0.12:5080;transport=udp SIP/2.0..Via:

0-16..a=silenceSupp:off - - - -..a=ptime:20..a=sendrecv..

He says that the INVITE line should have a DNIS (not sure what that is) 
in that field to indicate which number to route it to but that for some 
reason, my provider (Faktortel in Australia) is not supplying that 
information.

Does anyone know whether the problem is really at my provider's end or 
at my end, and if it's at my end, where ?

thanks,
pawz
