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

[Sebastien BOIRE-LAVIGNE]

I would see to avenues of investigation:

 

1.       I'm not sure it is OK to add the record-route on the re-invite for T.38, that may "confuse" your proxy.

2.       Since there is only one address in the "route", the proxy should determine the destination from the request line. The proxy doesn't seem to do that; I would ask the proxy vendor for the logic behind the routing.

Subject: [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
