What about other applications like VM? If MM or AAM is attached via SIP to SM can I still use it? Perhaps not G series Avaya gateways as they are (at 6.0) still dependent on CM for the analog station port operation??
If the CM fails are functionality with respect to the CM will not be available but SM will work without any problem.
The phones will behave as pure SIP user and will be able to use all the applications except CM which is already down.
As all the applications are integrated to SM they will work without any problem.
Yes all the Gateways will not work as they needs CM for all functionalities.
