There are two fax training modes: local training and point-to-point training.
The local training means that the gateways participate in the rate training
between facsimile terminals. In the local training mode, rate training is respectively
performed between facsimile terminals and gateways, and then the receiving
gateway sends the training result of the receiving facsimile terminal to the
transmitting gateway. The transmitting gateway finalizes the packet transmission
rate by comparing the received training result with its own training result.
The point-to-point protocol (PPP) training means that the gateways do not
participate in the rate training between two facsimile terminals. In this mode, rate
training is performed between two facsimile terminals and is transparent to the
gateways.
Perform the following configuration in voice entity view.
