Unanswered Question
Jul 10th, 2007

Hi Team,

Recently we migrated our voice gateway to support H.323 from MGCP for implementing a FAX Solution. Post Migration, we see that when we call a DID Number, the call goes through fine but when the caller disconnects the call, the IP Phone still keeps ringing.

The below is the config of the H323 Gateway.
