The values for this command apply only to the fax transmission speed and do not affect the quality of
the fax itself. The higher values provide a faster transmission speed but monopolize a significantly
larger portion of the available bandwidth. Slower transmission speeds use less bandwidth.
If the fax-rate command is set above the codec command rate in the same dial peer, the data sent over
the network for fax transmission exceeds the bandwidth reserved for RVSP. Because more network
bandwidth is monopolized by the fax transmission, we do not recommend setting the fax-rate value
higher than the codec command value. If the fax-rate value is set lower than the codec-command value,
faxes take longer to transmit but use less bandwidth.
This command only applies to VoIP peers.
Example
The following example configures a fax rate of 9600 bps for faxes sent to a dial peer:
dial-peer voice 10 voip
fax-rate 9600
