Chapter 40 Cisco IP Phones

Directory Numbers

devices. For N number of devices sharing the same line, both Maximum Calls setting and Busy Trigger setting must be set to N. This allows each shared line user to receive at least one call.

The shared line phone should not interact with the call that it does not receive (because the Line Control does not maintain call information). So, a newly registered device will not recognize any existing calls on that line. The newly registered device cannot resume any held call if the call started before this device was registered with the Line Control. For example, A and A’ share the same line, A is powered down (or logged out for the extension mobility user), and A’s receives an active call. After phone A is on and it registers with Cisco CallManager, A should not see the existing active call in this line.

If shared line phones’ calls should interact with each other, Cisco recommends that you set the maximum number of calls for all shared lines MCID devices to 2*N, where N is the number of shared line devices.

Shared Line Restrictions

•Do not use shared lines for Cisco CallManager Attendant Console pilot points or hunt group members. The phone that acts as the attendant console supports shared lines.

•Do not use shared line appearances on any Cisco IP Phone that requires auto-answer capability and do not turn on auto answer for a shared line appearance.

•Do not configure shared line appearances on the primary lines of the phones; for example, if two phones have a shared line appearance, only one of the phones should have the primary line configured as shared (the other phone should have the secondary line configured as shared).

•Barge and Privacy work with shared lines only.

•Cisco recommends that you do not configure shared lines for Cisco IP Phones, H.323 clients, and MGCP POTS phones; likewise, Cisco recommends that you do not configure shared lines for H.323 clients and MGCP POTS phones. If you configure the same shared line appearance for a H.323 client, a MGCP POTS phone, for example, NetMeeting, and a Cisco IP Phone, you cannot use the hold/resume feature on the H.323 client or MGCP POTS Phone.
