FAX T38 Redundancy Select the appropriate number.
The default is 1.
Fax Tone Detect Mode If you want the Gateway to detect the fax tone whether the Gateway is a caller or callee,
then select caller or callee. If you want the Gateway to detect the fax tone only if the
Gateway is the caller, then select caller only. If you want the Gateway to detect the fax
tone only if the Gateway is the callee, then select callee only.
FAX Tone Detect Mode This parameter has three possible values:
• caller or callee - SPA will detect FAX tone whether it is callee or caller
• caller only - SPA will detect FAX tone only if it is the caller

The default is caller or callee.

packets to the source address and port of the last received valid inbound RTP packet. If
disabled (or before the first RTP packet arrives) the SPA3102 sends RTP to the destination
as indicated in the inbound SDP.
The default is yes.
