Asterisk 1.4, T.38 passthru enabled, and works great with SIP extensions.
I want to send a fax from a T.38 capable SIP extension to a T.38 capable H.323 extension.
The voice part is okay. The call is established properly. However, when I start transmitting the fax, the SIP caller sends the ReINVITE, and the H.323 endpoint hangs up.
Any ideas?
Thanks in advance
