Good morning,
I have upgraded my asterisk from 1.4.26 to 1.4.35 (for resolve T38 issue) but after this upgrade the T38 pass-through not works with My FAX Ricoh (User-Agent: RicohIAF Version 2.0 (32)).
Before this upgrade my Fax works in reception but not in emission. After upgrade not works in reception (I have not tested in emision).
With debug on Asterisk when the Richoh send the RE-INVITE with T38 session asterisk send error 480

If see the chan_sip.c in process_sdp function I see:
/* Sanity checks */
if (!hp && !vhp) {
ast_log(LOG_WARNING, "Insufficient information in SDP (c=)...\n");
return -1;
}
and:
case 'c':
if (audio) {
if (process_sdp_c(value, &audiohp)) {
processed = TRUE;
hp = &audiohp.hp;
}
}
else if (video) {
if (process_sdp_c(value, &videohp)) {
processed = TRUE;
vhp = &videohp.hp;
}
}
break;
But in this case the Richoh send INVITE with just m=image part, is normal the hp and vhp pointer is null.
This problem is known or I open a bug ?
Best regards
Bernard
