[SIPForum-discussion] T38 Fax Transfer successful but disconnects

[Maciej Wasiel]

Hi,
Several things can cause the problem you're seeing. Do you have a network trace of the SIP/RTP/T38 traffic?

Subject: [SIPForum-discussion] T38 Fax Transfer successful but disconnects

Hi,

At the moment I'm having problems with T38 connections.

UA-A sends a Fax (2Pages!!!) to UA-B.
After G711 SDP connection, the Gateways both change to SDP T38.
UA-B receives the first page and then sends a Bye to UA-A.

UA-A disconnects the call and has to resend the FAX (Since only one page was sent!!!) Report says that Transfer was not successful.
UA-B prints out the first page and says that everything was successful.

Could there be an error in the T38 Stream???
