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 -- Marcin Gozdalik
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 On Wed, Oct 17, 2012 at 7:02 AM, Marcin Gozdalik <gozdal@gmail.com> 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 2012/10/17 Michael Collins <msc@freeswitch.org>

Hi Marcin, Post it somewhere, and I will take a look. Steve On 10/18/2012 05:30 AM, Marcin Gozdalik wrote:

You forgot some of the most critical parts of the info needed. Its a Cisco, but What model? What firmware? What rev of freeswitch? On Oct 17, 2012, at 9:02 AM, Marcin Gozdalik wrote:

FreeSWITCH is fairly old (2012-05-30), though I haven't seen many fax-related changes lately. I'd love to try git HEAD but it's fairly hard given tat new Debian packages complately change filesystem structure. The Cisco uses User-Agent Cisco-SIPGateway/IOS-12.x, no idea what model it is. Hope there is any way to debug this without upgrading to git HEAD. 2012/10/18 Brian West <brian@freeswitch.org>

I would highly recommend upgrading because we had a few bad bugs in and around that timeframe. /b On Oct 18, 2012, at 10:27 AM, Marcin Gozdalik wrote:
