Hi Marcin, Post it somewhere, and I will take a look. Steve On 10/18/2012 05:30 AM, Marcin Gozdalik wrote:
I have a pcap and can open in Wireshark. Starts with PCMU, switches to T.38. Wireshark (newest, 1.8.3) has trouble dissecting some packets (lots of UNKNOWN PER) and unfortunately I am no expert to tell if there is anything wrong.
Would anybody be able to help in debugging the issue having the PCAP? I can post it somewhere to download.
Best regards

Can you get a pcap of this and open in wireshark? I think it might give you a bigger picture of what's happening. -MC

Hi
I'm trying to send a fax from FreeSWITCH using T.38 (via Cisco SIP gateway) to a remote fax. It fails with some cryptic messages:
2012-10-17 15:51:30.467990 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 T4A expired in phase T30_PHASE_D_RX, state 27. An HDLC frame lasted too long. 2012-10-17 15:51:30.467990 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Status changing to 'The HDLC carrier did not stop in a timely manne r' 2012-10-17 15:51:30.467990 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Disconnecting 2012-10-17 15:51:30.467990 [DEBUG] mod_spandsp_fax.c:286 FLOW T.30 Changing from phase T30_PHASE_D_RX to T30_PHASE_E
I do have full SIP/RTP dump of such a call if it is of any interest. It seems to be a peculiar interoperability issue, as this setup is used as a email2fax/fax2email gateway and it works quite well.
Could anybody recommend any steps I could try to debug/fix the issue?
Best regards
