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 effect the V-GW. Please advise what is the reason that I'm getting this message and how can I avoid it? -- Regards, Ahmed Munir Chohan
