SipRegisterReceived

The SipRegisterReceived event is sent to an application when the media engine receives a SIP REGISTER message. If your application wants to support SIP oriented registrar functions, then you will have to process this event.

When your application receives this immediate event, it will also receive the address of a REGISTER_DETAILS structure in memory. Your application can use the contents of this structure to determine if you want to accept or decline the registration request.

When an application receives this event, the media engine event callback procedure SIPCALLBACKPROC will have a non zero value assigned for the pEventData parameter. This value is a pointer to the REGISTER_DETAILS structure which contains additional information for this event.
