Operation

The phones supported by the push server are called web-enabled phone sets.  These particular models support a web language called WML.  When a phone is enabled or a user performs a login via the telephone set, the phone will connect to the server and notify it of the phone's IP address, extension, MAC address and type of phone set.

The DV2000/DV4 will monitor all calls destined for these sets and push mailbox information to their screens.  If no mailbox is associated with the calling number, then no data other than the calling number will be displayed.   The figure below shows a typical push screen, showing a call from 3320 to 2006, where 3320 is associated with the mailbox for subscriber Jon Doe.

911 Monitoring is an optional feature that has the ability to notify several extensions at once if any extension has dialed 911.  This notification will also cause the phone to beep 3 times to alert the user.  The figure below shows the push screen for a 911 call being made from extension 3320; the alert has been pushed to extension 2006.

Finally, the figure below provides a graphical overview of how information is routed for calls made by a subscriber on the DV2000/DV4 to an IP phone.  The information pushed to the IP phone will appear at the same time as the call itself, making it easy for the user to determine exactly who is calling.
