Hello!
I collected tcpdump between Freeswitch and Audiocodes MP-114 and found something strange. The sequence of packets is:
FS INVITE with SDP
MP 100 Trying
MP 180 Ringing
MP 200 OK with SDP
FS/MP RTP/RTP
MP ReINVITE with SDP
FS 100 Trying
---- long pause and call disconnected
MP BYE
FS 200 OK with SDP !!!!! CSeq: INVITE !!!!!
FS 200 OK CSeq BYE
FS 200 OK with SDP !!!!! CSeq: INVITE !!!!!
FS 200 OK with SDP !!!!! CSeq: INVITE !!!!!
FS 200 OK with SDP !!!!! CSeq: INVITE !!!!!
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?
Hello!
I need help with fax configuration. My network is:
PSTN E1 --- Cisco AS5350 -- Freeswitch -- Audiocodes MP-114 -- Fax
FS version: FreeSWITCH Version 1.0.head (git-062f07f 2011-07-16 12-35-25 +0200)
Audiocodes firmware: 6.00A.038.004
I can't get faxes working :( In FS profiles there is a parameter <param name="t38-passthru" value="true"/>
Cisco DP fax settings:
fax-relay ecm disable
fax rate 9600
fax protocol t38 ls-redundancy 2 hs-redundancy 1 fallback pass-through g711alaw
no vad
On Audiocodes there is also T38 enabled (as I think) but there is no T38. There are messages on MP-114:
ErrMgs=16 T38Decoder received Non-T38 Packet
