You didn't provide all of the debug requested.

Please provide "a pcap showing the fax message traffic" (including SIP and the UDPTL)

Also, please attach your entire udptl.conf and sip.conf files. *Please attach the files to the issue and do not past them inline inside of a comment*

If this notice comes, it occurs repeatedly unless I need to restart the asterisk service.

To demonstrate this, please provide an Asterisk full log with VERBOSE and DEBUG messages enabled at level 5. https://wiki.asterisk.org/wiki/display/AST/Collecting+Debug+Information

It's hard to understand the behavior from your description. Is Asterisk responsive to calls, commands or anything else after the error occurs? Or is the error just scrolling the log with no other ill effects?

> Hi,
> I configured Asterisk 10 for inbound fax, for couple of weeks I didn't see any issues until 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: Resource temporarily unavailable
> If this notice comes, it occurs repeatedly unless I need to restart the asterisk service. For some reason it also effecingt the V-GW. There is no issue found in the V-GW side.
> I first open this ticket in 'Asterisk Support', they advised they there might be bugs in Asterisk 10.4.2. Is there a fix in Asterisk 10.12? If yes, please advise at earliest.
