[asterisk-users] Movistar sip Mexico

[Damian Gonzalez]

Hello,

Thanks for the quickly response. I have only G729 in the peer but I have
t38pt_udptl= yes

If I put t38pt_udptl=no , asterisk reject the call with 488 code.

The problem is that Movistar send T38 codec in all calls and I need ignore
only if in the SDP I have G729 and T38 (18 and 101), but if I have only T38
I have to negociate a fax call.

Thanks.
