Chapter 40 Cisco IP Phones

Directory Numbers

the call on hold, user can retrieve the call from the Cisco IP Phone 1 or Cisco IP Phone 2. When User 2 dials directory number 2000 for the second call, only Cisco IP Phone 2 and Cisco IP Phone 3 ring.

The following example demonstrates how an H.323 client, MGCP POTS Phone, and Cisco IP Phone with the same shared line appearance, directory number 2000, can use the Call Forward Busy Trigger and the Maximum Number of Calls settings. This example assumes that two calls occur. The following values have been configured for the devices:

–H.323 client—Configured for a maximum call value of 1 and busy trigger value of 1

–MGCP POTS Phone—Configured for a maximum call value of 1 and busy trigger value of 1

–Cisco IP Phone—Configured for a maximum call value of 2 and busy trigger value of 2

When User 1 dials directory number 2000 for the first call, all three devices ring. The user for the Cisco IP Phone picks up the call; when the user for Cisco IP Phone puts the call on hold, the user(s) for H323 client and MGCP POTS Phone cannot retrieve the call. If User 2 dials directory number 2000 for the second call, only the Cisco IP Phone rings. Users for the MCGP POTS Phone or the H.323 Client cannot answer the call.

For information on Maximum Number of Calls setting, refer to the “Directory

Number Configuration Settings” in the Cisco CallManager Administration

Guide.

The check box, Update Directory Number of All Devices Sharing this Line, in the Directory Number Configuration window, determines whether a shared directory number gets updated to all devices sharing the number. Refer to the “Update Directory Number of All Devices Sharing this Line” section on page 40-30for more information.

A shared line phone should not be able to interact with the call that it rejects, due to the limitation of the maximum number of calls per DN or for other reasons. For example, A and A’ share the same DN. A’ and A have the maximum number of calls set to 1 and 2, respectively. When C and D call the share line DN, A’ answers these two calls. A can only interact with the first call, as it rejects the second call due to its own maximum number of calls per DN limitation. For this reason, Cisco recommends that the same value be configured for the maximum number of calls for all shared line MCID
