Functional Notes
When a fax tone is enabled, the tone is eligible to initiate either modem-passthrough or T.38 handling,
depending on the command entered. T.38 fax tone commands take priority over modem passthrough fax
tone commands. For example, in the default configuration with all commands enabled, any detected tone
on a call would cause a reINVITE to T.38, as long as T.38 is enabled on the user (or primary rate interface
(PRI/CAS trunk). If T.38 is not enabled, the call would be reINVITED to G.711 in modem passthrough
mode.
Usage Examples
The following example disables t30-cng fax tone for modem passthrough mode:
(config)#no voice fax-tone modem-passthrough t30-cng
60000CRG0-35E
Command was introduced.
Command default was changed so that only the v21-preamble tone is
enabled by default for the T.38 tone list.
