Extension Monitoring and Call Pickup
This feature allows you to monitor the call state of other extensions and to answer calls
to these extensions. It is very useful for a user, especially a phone receptionist, to know
the call state of other phones so that he or she knows if a call can be successfully
made to a phone.
L Note: Your VoIP PBX must support this functionality.
• Single subscriptions (RFC 4235 compliant)
• Event-list subscriptions (RFC4662 compliant); this feature is only available from
firmware release 7 onwards.
