Cisco is probably referring to T.38 which is something completely
different. Cisco is actually one of the worst companies in regards to
SIP. They speak weird edge-cases of the protocol and force G.729 onto
T.38 actually is a protocol you could have a lot of fun with as it's
fairly complicated, but flexible and has lots of broken implementations
even on devices like the AVM Fritz!Box. There are Fax machines which
will refuse to work with T.38 on a Fritz!Box as they will reliably
trigger that bug.
