Note

The SBC 1000 supports fax on all TDM interfaces (PRI, BRI, FXS, and FXO). TDM calls, which have both call legs as TDM, use T.30 protocol. If either one or both of the call legs are IP (SIP), then the calls use T.30 protocol or inband audio. The SBC 1000 supports both the G3 and Super G3 fax protocols.
