Re: [Megaco] Re: Descriptor state after out of service

G'Day Tom,

Servicechange change does not "only" change state. Depending on the method there
are certain procedures around the Servicechange. ie. for Servicechange =
Graceful it is expected that the MGC should subtract the termination when a call
if finished or expiry. When this happens according to graceful the terminations
will be put out of service.

Cheers, Christian

Does the descriptor remain on termination database but inactivated or does they are total flushed. Thus if this termination is put "in service" by MGC or MG then what will be the state of descriptor i.e. they are reapply/reactivated on the termination or not.
