Rohan, Thanks so much for your quick and detailed response!
Voice mail sessions are generally short lived and transient, so I would like to know what is the use for registering per user in case of voice mail scenarios. Is this more for a scenario where the user registers with the main proxy (e.g. web client) and then all entities (e.g. messaging notifier) can register for that user with callee capabilities.
