Note that the MGC is not required to audit anything.  If it chose, it
could tear down all the contexts to put the MG back in a known state.
The methodology for syncing itself with the MG is left up to the MGC.

Hi
Usually MGw would send ServiceChange with Disconnected method to
indicate MGC that the communication link was broken for while and now it
has recovered.
MGC would then initiate Audit Procedures so as to come in sync with MGw.

Hi,

If we have a MGC and MGw communicating over UDP control link and below
sequence happens .

1) Assuming the link is up towards the MGw and Supervision messages are
sent (empty root audits) and replied from MGw.
2) Control link in MGw goes down
3) Control link in MGw comes up before (MGC) has detected that the
communication was down
4) MGW start sending service change messages to MGC.

How should the MGC handle these messages?

Thanks

Regards
Vijay
