[Freeswitch-users] Incoming call from registered gateway with DID in To: not URI

[Steven Ayre]

Hi everyone,

I have a gateway registering to numbergroup.com, this is the configuration:

<gateway name="numbergroup">
    <param name="realm" value="sip.numbergroup-services.com"/>
    <param name="username" value="XXXXXX"/>
    <param name="password" value="XXXXXX"/>
    <param name="register" value="true"/>
    <param name="extension-in-contact" value="true"/>
    <param name="caller-id-in-from" value="true"/>
    <param name="ping" value="60"/>
    <param name="ping-max" value="10"/>
    <param name="ping-min" value="1"/>
    <param name="retry-seconds" value="5"/>
    <param name="expire-seconds" value="60"/>
</gateway>

Incoming calls from my DID to a SIP URI on the server work fine.
However I'm having problems sending it to the SIP Trunk (the
registration above).

The call arrives on the server fine, but the URI is the
username at sip.numbergroup-services.com. The DID is in the To: header

destination_number in the dialplan is the username not the DID as a
result. Does anyone know how to configure the gateway so that the
destination_number would contain the DID from the To header instead?

Here's the INVITE:
