I'm testing 1.4.5 (no modifications) with E1 card and i've found problem.
I've this scenaro
FAX -> SIP - ATA -> asterisk -> E1 port A --loopback--> E1 port B -->
When jbenabled is off FAX is delivred OK. But when jbenable = on FAX are
failing in almost every line. I've compared WAV extracted from network
with WAV recorded (app monitor) before it gets to iaxmodem and there is
small differences. Network jitter is about 2ms (lab environment).
Where could jitterbuffer modifies frames? I've tried to disable plc in
plc.c but without success. Any idea?
thanks in advance
