Successful faxing via VoIP
Why reduce the baud rate?
Jitter (disturbance signal, clock ticking) and bad latencies can lead to corrupt fax transmission. When the fax machine detects a poor transmission, the entire fax is interrupted. By reducing the baud rate to 9600 bps, it is more likely that all packets can be successfully transmitted through the network.
Why should ECM (Error Correction Mode) be switched off?
In the analogue world, the Error Correction Mode is certainly a help to stabilize and improve the transmission. When sending faxes via VoIP, this error correction can lead to problems and transmission abortions.
We recommend that this error correction be switched off if faults occur.
