Extension Monitoring And Call Pickup; Busy Lamp Field (Blf) Feature - Doro ip810c Manual

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.
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.
