[SIPForum-discussion] False Routing after Re-Invite with SDP T38

Hi,
I got a Problem with a FAX Server and a SIP Proxy:
The incoming call looks OK and the Gateway / Fax Server use G711 in the SDP.
Our fax Server cannot use G711 and sends a Re-Invite to the Gateway (over the Proxy) with the SDP Parameters of T38.
Now the error happens:
The Proxy receives the Invite and forwards this Invite back to the FAX Server (instead to the Gateway).
That means either the Invite is not correct, or the Proxy is going something wrong.
Here the filtered error (from the FAX Server 10.59.130.36) :
Gateway Proxy FAX Server
10.244.254.11 10.241.42.252/253 10.59.130.36
498888888888 491234567
--------Invite------------>
--------Invite------------> Packet 1
<------- Trying --------- Packet 2
<-------200 OK --------- Packet 3
---------ACK------------> Packet 4
<--------Invite ---------- Packet 5
--------Trying------------> Packet 6
--------Invite------------> Packet 7
Why is Packet 7 send to the FAX Server:
