Question

How do I use SIP Subscribe/Notify with VoIP calls on Blueworx Voice Response?


Cause

Blueworx Voice Response and Unified Messaging together support the use of the SIP Subscribe/Notify methods for notification of MWI (Message Waiting Indications) according to RFC3265 (SIP - Specific Event Notification).


Answer

Subscribe/Notify is automatically enabled by starting the UM IMC_Subscribe custom server, which takes over the role of handling MWI notifications from the standard MWISERVER process.
