...ntil today. The setup I configured for inbound fax is quite simple i.e. Cisco Voice GW sends the fax calls to Asterisk using T.38 protocol and later Asterisk stores/forwards the fax to specific end user. The configuration I made in sip.conf for enabling T38 is listed below; t38pt_udptl = yes,fec,maxdatagram=400 faxdetect = t38 And in udptl.conf, I just uncommented 'use_even_ports = yes ;' and rest of it set as default. Here is the error I'm usually seeing in Asterisk side; [Jan 15 14:13:28] NOTICE[20514] udptl.c: UDPTL (SIP/10.3.22.6-00000ad6): Transmission error to 10.3.22.6:18428: Re...

Anyone have any testing experience with T38 and HT-502 Grandstream? I just want to confirm that t.38 is working on this device.

Hello, I have been trying to setup asterisk (1.6.2.0) to receive fax. I am able to receive faxes sent from a zoiper softphone connected to asterisk. I have some DID numbers (with T.38 support) forwarded to my asterisk pbx. I am not able to receive faxes from these numbers. The error I get on the asterisk console is "phase_e_handler: Error transmitting fax. result=49: The call dropped

...onnected with an error phase_e_handler: Error transmitting fax. result=13: Unexpected message received. What could be the reason for this error? Is this a problem with misconfiguration of audiocodes or asterisk.

Hello, at first, thanks for helping! In the meantime, I have done a lot of research and trial and error, and I could solve that specific problem. Obviously, the dialplan application "Answer" was playing a key role here. My original dialplan snippet (which produced that problem) was: exten => _00., 1, NoOp() same => n, Set(FAXOPT(gateway)=yes) same => n,

Hello list, We're currently facing some issues concerning T.38 gateway faxing. This is a device used almost exclusively for receiving faxes.

This message is pointed directly to Steve Underwood. I tought it would not be nice to directly email him with a question that interests a good part of the Asterisk community, so here it is. :) Steve, remember a few days ago when we discussed about issues on Asterisk 1.6.1.13 and T.38 fax reception? Well I opened an issue on Mantis (https://issues.asterisk.org/view.php?id=16756) and turns out it
