Cisco 7940 Manual&Nbsp;

3.2. Message Waiting Indicator (MWI)
With the Outboard Proxy SIP extended feature set, a SIP telephone that supports IETF RFC 3265
and MWI Draft 4 (Subscribe/Notify method) will illuminate/extinguish its MWI lamp when
voice messages are left/read for that extension. Since the Cisco 7940/7960 SIP phones support
only the unsolicited Notify method for MWI, this feature is not currently supported in
Communication Manager.

4.1. Administer Users on the Avaya Converged Communications
Server
