To enable the use of the ITU-T T.38 standard for faxing,
select yes. Otherwise, select no.
T.38 is supported by the SPA2102 and the SPA8000. The
SPA2102 supports a single T.38 connection. The SPA8000
supports one T.38 connection for each of its four modules
(Line 1-2, 3-4, 5-6, and 7-8). The SPA8000 supports a
maximum of four connections, but it does not support two
fax devices connected to the same module.
The default is yes.
Select the appropriate number.
The default is 1.
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.
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
• callee only - SPA will detect FAX tone only if it is the
callee
The default is caller or callee.
(SPA3102 and AG310only) Enable symmetric RTP
operation. If enabled, the SPA3102 sends RTP 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.
