US 12,184,813 B2 · Call control instance changeover

Abstract

In an example embodiment, a solution is provided that provides multiple call control service instances for each media server instance. When one of the call control service instances needs to be updated, the media server is instructed to direct newly received voice calls to another of the call control instances. The call control service instance to be updated remains operating normally until all voice calls handled by that call control service instance have ended naturally, but any new calls received during that time are directed to one of the other call control service instances. Only once all the voice calls handled by the call control service instance to be updated have ended is that call control service instance actually updated, without having had to disconnect a live call.
