Hi to all,
it is my first post here, i’m a new user of asterisk, i’ve searched on internet for my problem but i’ve not find nothing…
I’ve Asterisk 1.4.18, i’m tryng to receive fax on my estension with support t38, the trunk is with sip protocol and support t38.
When my estension try to receive fax i have this error:
[Nov 14 13:11:05] WARNING: chan_sip.c:12114 handle_response_invite: RTP re-invite after T38 session not handled yet !

I’ve read a lot of posts on internet but i don’t known what i’ve to do… Can anyone suggest me how to do for resolve so… Or How i can read something ?
Thanks for all
