I have an Asterisk system that is registering to FusionPBX to use as a proxy B2BUA for outbound calls. The Asterisk system is setting a callerID number for the outbound call, and FusionPBX is passing that on to the trunk provider as RPID. The problem is that the FROM: header in the sip packet is showing up with strange headers:
INVITE sip:+1NXXNXXXXXX@siptrunkprovider.com SIP/2.0
Via: SIP/2.0/UDP 77.88.99.111:5060;rport;branch=z5hG4bKaj39jy5mHcX1H
Max-Forwards: 69
From: "12123334444" <sip:FreeSWITCH@siptrunkprovider.com>;tag=e5eRgBFXDe9Nc
To: <sip:+1NXXNXXXXXX@siptrunkprovider.com>
Notice how the FROM: is showing "FreeSWITCH", and is showing the destination SIP provider's endpoint. Why is this happening?
I have tried setting "Caller-ID-in-From" and this hasn't helped.
