[asterisk-users] Now to set contact username and from username idependently

[Benoit Panizzon]

Hello

Finally I figured out, how our SBC does matches invites to
registrations with the Contact header.

But now I run into a Problem:

How do I set the contact header of an invite different to the From
header?


INVITE sip:called-id at URI SIP/2.0
Via: SIP/2.0/UDP IP:5060;branch=z9hG4bK495c70cc
Max-Forwards: 70
From: "SBC TEST" <sip:callerID at IP>;tag=as2c330ac5
To: <sip:called_id at URI>
Contact: <sip:user-from-reg at IP:5060>

in my 

[sip-provider]
type=peer
;fromuser=user-from-reg
;username=user-from-reg
secret=hidden
host=URI
outboundproxy=IP of Proxy

As soon as I set either fromuser or username, this also overwrites the
callerID and then of course the CallerID which should be sent over the
trunk is not correct anymore.

And of course because the CallerID can be different for each call (it's
a trunk) I cannot set it with CallerID= in the peer definition.

Am I missing something?
