T38 and codecs negotiation
...t38 is globally enabled p->t38.jointcapability
and udptlportno are always true even so the call is never rejected.
As this behavior caused me some problems with a customer I modified, for the
moment, the line 5638 as follows:
if (!p->t38.jointcapability || !udptlportno || p->t38.state == T38_DISABLED)
cause if I understand well the code if there is no fax request in the INVITE
SDP p->t38.state is set to T38_DISABLED.
This did the trick for me but I don't know the implications of such change
and if it is correct to manage it this way.
Kind regards,
Federico Cabiddu

T.38 Peer Negotiation Fails
...stablished with
Broadvox. During negotiation, Asterisk sends a SIP re-invite (T38
switchover) to Broadvox with the Asterisk server's IP address in the
Connection Information (c) instead of the Linksys ATA's IP address.
This causes the negotiation to revert back to t38state zero
(chan_sip.c: T38_DISABLED), and shortly after the ATA hangs up.
What is a bit odd about this, is that Asterisk says it's about to
establish a peer to peer UDPTL connection :
chan_sip.c: Sending reinvite on SIP
'1057817983_43059159 at xxx.xxx.xxx.xxx' - It's UDPTL soon redirected
to IP yyy.yyy.yyy.yyy:16468...
