Hi,

I think even if fully resolved event descriptor is not sent, MGC should not
send next message to NULL context.



Cheers !!!

Hi Ramesh,

The Event descriptor on termination A6 is over-specified (i.e. it contains *
wildcard). It may be possible that MGC is expecting fully resolved Event
descriptor in ADD response.

Thanks
