[Freeswitch-dev] FreeSWITCH and Twilio

[Michael Nielsen]

Hello everyone,

I'm trying to setup FreeSWITCH with Twilio - to place outbound calls.

I've created a SIP trunk in Twilio and are now trying to terminate calls
via Twilio - all 10 digit calls should go this way (2 digit country code
and 8 digit number - Danish numbers).

This is my twilio.xml in sip_profiles/external:

<include>
  <gateway name="Twilio-outbound">
    <param name="username" value="MY-USER"/>
    <param name="password" value="MY-PASSWORD" />
    <param name="proxy" value="MY-SIP.pstn.twilio.com"/>
    <param name="register" value="false"/>
  </gateway>
</include>

This is my 02_twilio.xml in dialplan/default/:

<include>
  <extension name="international.twilio">
    <condition field="${toll_allow}" expression="international"/>
    <condition field="destination_number" expression="^(\d{10})$">
      <action application="set"
data="effective_caller_id_number=${outbound_caller_id_number}"/>
      <action application="set"
data="effective_caller_id_name=${outbound_caller_id_name}"/>
      <action application="bridge" data="sofia/gateway/Twilio-outbound/$1"/>
    </condition>
  </extension>
</include>

When I try and make a call for a Danish number (for example 4512345678) I
get a "Bad Request 400".

This is my FS log:
