Hylafax, FaxGetty

[cantVOIP]

The incoming faxes have a descent quality, but the faxes we send look awful. Has anyone made any changes to improve the quality of faxes sent from your PBX?

Any advice would be appreciated. Thank you in advance!

For starters, I'd make sure your outbound fax is set for 9600 baud instead of 14400.

I've changed the value of the following. Is this the correct value to change?
(/etc/hylafax/config.ttyIAX0)
ModemRate: 9600

I implemented the change, restarted iaxmodem service "service iaxmodem start" but the quality is still the same as before the change.

Hard to say. Is your inbound trunk or provider to the fax the same as your outbound one? If the VOIP connection has jitter, it will really kill the fax transmission.
