Subject: MGC Failure

Hi Everybody,

I got two questions.

1. How does the MG detect a failure of it's controlling MGC? One potetial way would be thru the Notify command. But Notify does not have an ACK? Does the protocol say anything about this?

2. The H.GCPMEGACO/H.248 document says the following:

Page 62
-------

If a new Media Gateway Controller is detected, the Media Gateway starts transmitting outstanding commands to that new agent. Responses to commands are still transmitted to the source address of the command.

Page 70
-------

When the MGC initiates a Handoff, the handover should be transparent to Operations on the Media Gateway. Commands in progress continue, transaction replies are sent to the new MGC, ...

So where do the replies/responses go, to the old MGC (source address of the command) or new MGC?

BTW I am referring to the following document:

ftp://standards.nortelnetworks.com/megaco/docs/Wash99/MegacoH248v9Chgs.pdf

Any response will be appreciated.
