Summary:                    Four Dahdi Events not recognized from chan_dahdi to
disable Echo Cancelation
Description: 
I am using Dahdi 2.3.0.1 with a Sangoma A108D and MG2 echo canceler and
Asterisk 1.6.2.9.
I´ve found out that when i send a fax from another server with hylafax
and iaxmodem the CED tone is not recognized from chan_dahdi even if dahdi
itself put a kernel message that echo cancelation is turned off.

i also see in debug log that there are 4 new events from dahdi which are
not recognized in chan_dahdi.c in the 1.6.2 version.

the diff which is attached, add these 4 events to chan_dahdi and also turn
off or on, like thte event says.
