Abstract
A facsimile transmission device implements silence suppression based on a state of a facsimile call and detected facsimile signals. A decision process implemented in the facsimile device can determine when silence suppression should be enabled. The facsimile device may be an IP media gateway connected between a PSTN and an IP network, or may be an IP endpoint. The determination of when to enable silence suppression can be based on the state of sending or receiving facsimile transmissions including facsimile operations and/or signaling. The decisions can be based on the type of facsimile transmission including G3 type or SG3 type facsimile transmissions. By enabling silence suppression during facsimile transmissions, significant reductions in bandwidth requirements can be achieved for the facsimile transmission while maintaining facsimile transmission quality.
