Hi sasnak,
Thank you for using the Support Forum. Please see the System Administrator Guide for information on changing the speed of fax transmissions. If you are unable to find what you need in the System Admin guide please consider contacting your support centre for further assistance.
Is there a way to turn off ECM and change the baud rate down to 9600 to send FAX pages successfully over a VOIP line? I've tried changing the Starting rate to a "Forced 4800 bps" but still no luck. I get Error 033-502.
Thanks,
Brad
