[Freeswitch-users] fax goes out at 9600 but not at 14400

[Steve Underwood]

Hi,

The commonest reason for 14,400 failing and 9600 working is the call is 
going out through a poor quality ATA. A *lot* of ATAs seem to badly 
degrade the analogue signal. If it were a digital domain issue, like 
packet loss or a jitter buffer messing up the timing of the signal, this 
should affect 9600 just as much as 14,400.

Regards,
Steve
