Hi,

 

We’re using a freeswitch which bridges calls between two networks: private and public. The server has two interfaces. The calls originate from the private network and are bridged using the public sip profile.

For some reason I cannot get the 180 and 183 messages passed back from the outbound leg to the inbound leg when sending calls over the public sip profile.

 

Both sip profiles have been set with:

    <param name="inbound-bypass-media" value="false"/>

    <param name="inbound-proxy-media" value="true"/>

 

The below dialplan is hit when a call arrives on the LAN(private) interface of the freeswitch.

 

<?xml version="1.0" encoding="utf-8"?>

<include>

  <context name="local">

    <extension name="route_to_public">

      <condition field="destination_number" expression="(\d+)$" require-nested="false">

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

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

        <action application="set" data="continue_on_fail=false"/>

        <action application="set" data="ignore_early_media=false"/>

        <action application="set" data="sip_copy_custom_headers=false" />

        <action application="set" data="sip_ignore_reinvites=false"/>

 

        <action application="set" data="effective_caller_id_number=${translate(${caller_id_number} To_International)}" />

        <action application="set" data="effective_caller_id_name=${translate(${caller_id_number} To_International)}" />

        <action application="set" data="destination_number_translated=${translate(${destination_number} To_International)}"/>

        <action application="bridge" data="sofia/gateway/${distributor(public_gws ${sofia(profile public_eth1 gwlist down)})}/${destination_number_translated}" />

      </condition>

    </extension>

  </context>

</include>

 

Any ideas why the 180/183 are not relayed from outbound leg back to inbound leg? A trace shows these messages do arrive on the outbound leg.
