Hello!<br>
<br>
<br>
I collected tcpdump between Freeswitch and Audiocodes MP-114 and
found something strange. The sequence of packets is:<br>
FS INVITE with SDP<br>
MP 100 Trying<br>
MP 180 Ringing<br>
MP 200 OK with SDP<br>
FS/MP RTP/RTP<br>
MP ReINVITE with SDP<br>
FS 100 Trying<br>
---- long pause and call disconnected<br>
MP BYE<br>
FS 200 OK with SDP !!!!! CSeq: INVITE !!!!!<br>
FS 200 OK CSeq BYE<br>
FS 200 OK with SDP !!!!! CSeq: INVITE !!!!!<br>
FS 200 OK with SDP !!!!! CSeq: INVITE !!!!!<br>
FS 200 OK with SDP !!!!! CSeq: INVITE !!!!!<br>
<br>
Thinking this is a problem of T.38 operation. Sometimes, IMHO,
Freeswitch is buffering??? 200 OK response and session can not be
established. Where may I place dump for gurus may look at it?<br>

Hello!<br>
<br>
I need help with fax configuration. My network is:<br>
<br>
PSTN E1 --- Cisco AS5350 -- Freeswitch -- Audiocodes MP-114 -- Fax<br>
<br>
FS version: FreeSWITCH Version 1.0.head (git-062f07f 2011-07-16
12-35-25 +0200)<br>
Audiocodes firmware: 6.00A.038.004<br>
I can't get faxes working :( In FS profiles there is a parameter
<param name="t38-passthru" value="true"/><br>
Cisco DP fax settings:<br>
fax-relay ecm disable<br>
fax rate 9600<br>
fax protocol t38 ls-redundancy 2 hs-redundancy 1 fallback
pass-through g711alaw<br>
no vad<br>
<br>
On Audiocodes there is also T38 enabled (as I think) but there is
no T38. There are messages on MP-114:<br>
ErrMgs=16 T38Decoder received Non-T38 Packet<br>
and<br>
