Usage
For users using this mode, Communication Manager treats a fax call as
an ordinary voice call. Turn off special fax handling.
For users using this mode, Communication Manager uses the Avaya
proprietary relay mode for fax transmissions over IP network facilities
only between Avaya devices. This mode may be coupled with
Redundancy.
For users using this mode, Communication Manager uses the Avaya
proprietary pass-through mode for in-band fax transmissions over IP
network facilities only between Avaya devices. This mode may be
coupled with Redundancy.
For users using this mode, Communication Manager uses the T.38
protocol for fax transmission over IP network facilities.
For users using this mode, Communication Manager uses the T.38
protocol for fax transmission only if the protocol can be successfully
negotiated with the peer SIP entity.
Otherwise, Communication Manager falls back to G.711 for fax
transmission. This mode requires a G.711 codec to be administered on
the ip-codec-set screen.
