Hi,

I have a sip provider who requires me to set the username to be the same as the outbound caller id for the gateway (trunk) to them.

Is there a way to do this dynamically for each call?

e.g.

<include>

    <gateway name="SIP-Provider">

      <param name="username" value="${outbound_caller_id_number}"/>

      <param name="password" value="password"/>

      <param name="realm" value="1.2.3.4"/>

      <param name="proxy" value="1.2.3.4"/>

      <param name="expire-seconds" value="800"/>

      <param name="register" value="false"/>

      <param name="retry-seconds" value="60"/>

      <param name="context" value="public"/>

    </gateway>

</include>

Cheers

Liam
