[Freeswitch-users] Sorting through a list of conditions

[Ken Fulmer]

That is exactly what we needed. I’m still a little new to matching with regular expressions.

 

Thanks!

Ken,

 

ever heard of regexp ? :)

 

In this case, I think you need to use one, or to add one extension per fax line, which can be more readable and managable.

Other solution would be to use an external DB with XML CURL.

 

The regexp solution would be:

 

   <condition field="caller_id_number" expression="^XXXXXXXXXX|XXXXXXXXXX|XXXXXXXXXX|XXXXXXXXXX|XXXXXXXXXX$"/>

 

Another smart (I think) way to do that would be to create and dedicate a new SIP Profile on a specific IP or port to fax handling (of course, that's only possible if you use a dedicated SIP account for fax).

 

I think the ability to split FreeSWITCH into multiple SIP Profiles (and so multiple threads) is something that should not be underrated.

It's really easier to manage and you dont break everything when you test some new parameters on the profile.

Most serious SIP devices should allow to register to a specific port, so you can use something else than 5060 (Ok I admit some shitty gear don't allow that, but most of the ATAs I know are ok).

We’d like to match on either Caller ID or ANI for outbound faxes and lock them to PCMU.

 

Here’s what we’ve been using:

 

<extension name="FAX-LCL-7D">

   <condition field="caller_id_number" expression="^XXXXXXXXXX$"/>

   <condition field="destination_number" expression="^9(\d{7})$">

       <action application="export" data="sip_append_audio_sdp=a=fmtp:18 annexb=no"/>

       <action application="export" data="nolocal:absolute_codec_string=PCMU"/>

       <action application="set" data="hangup_after_bridge=true"/>

       <action application="bridge" data="sofia/external/$0 at X.X.X.X"/>

       <action application="set" data="instant_ringback=true"/>

       <action application="set" data="ringback=${us-ring}"/>

   </condition>

</extension>

 

If we use a list and break=on-false, searching stops after the first non-match. If we use break=on-true, it stops after the first match, and we get no digits to send upstream. If we use break=never, it applies the digit match to all numbers, regardless of Caller ID. I realize this is all normal behavior.

 

Is there a way to sort through a list of Caller ID’s, match one, and then match the outbound digits? We’re trying to avoid having to create a dial-plan entry for every Caller ID.

 

Here’s what it *might* look like with multiple internal fax lines:

 

<extension name="FAX-LCL-7D">

   <condition field="caller_id_number" expression="^XXXXXXXXXX$"/>

   <condition field="caller_id_number" expression="^XXXXXXXXXX$"/>

   <condition field="caller_id_number" expression="^XXXXXXXXXX$"/>

   <condition field="caller_id_number" expression="^XXXXXXXXXX$"/>

   <condition field="caller_id_number" expression="^XXXXXXXXXX$"/>

   <condition field="caller_id_number" expression="^XXXXXXXXXX$"/>

   <condition field="caller_id_number" expression="^XXXXXXXXXX$"/>

   <condition field="caller_id_number" expression="^XXXXXXXXXX$"/>

   <condition field="destination_number" expression="^9(\d{7})$">

       <action application="export" data="sip_append_audio_sdp=a=fmtp:18 annexb=no"/>

       <action application="export" data="nolocal:absolute_codec_string=PCMU"/>

       <action application="set" data="hangup_after_bridge=true"/>

       <action application="bridge" data="sofia/external/$0 at X.X.X.X"/>

       <action application="set" data="instant_ringback=true"/>

       <action application="set" data="ringback=${us-ring}"/>

   </condition>

</extension>

 

 

Thanks,

 

Ken Fulmer
