Hi,
Few months back I configured Asterisk 11.6.0 for an outbound fax using T.38
protocol as listing down the flow below;
Asterisk Fax server -> (IP) -> Cisco VGW ->(IP) -> Carrier
The issue I'm currently getting when Asterisk receives warnings as listed
below, it is overloading the Cisco VGW, therefore need to restart Asterisk
service or sometimes reboot VGW to clear these warnings.
[Mar 24 09:25:01] WARNING[28645][C-00000004] app_fax.c: Unable to write
frame to channel; Resource temporarily unavailable
[Mar 24 09:25:01] WARNING[28613][C-00000002] app_fax.c: Unable to write
frame to channel; Resource temporarily unavailable
The configuration in sip.conf for T.38 is listed below;
t38pt_udptl = yes,fec,maxdatagram=400
faxdetect = t38
Udptl.conf;
udptlstart=4000
udptlend=4999
udptlfecentries = 3
udptlfecspan = 3
use_even_ports = no
Please advise at earliest to overcome this issue.
