Hi Philippe,

It will not work Give it a try if you get a chance.

It has never worked with "shared lines" and I can't see how it ever would.

Shared Line Restrictions

The following restrictions apply to shared lines:

•Do not use shared lines for Cisco Unified Communications Manager 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 Unified IP Phone that requires autoanswer 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, cBarge, and Privacy work with shared lines only.

•Cisco recommends that you do not configure shared lines for Cisco Unified 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 Unified IP Phone, you cannot use the hold/resume feature on the H.323 client or MGCP POTS phone.

•Cisco recommends that you do not configure shared lines for Cisco Unified IP Phones 7905, 7912, 7940, and 7960 that are running SIP because these phones cannot pick up held calls on shared lines nor can they use the shared-line features Single Button Barge/cBarge, Barge, cBarge, and Privacy.

•Cisco Unified IP Phones 7906, 7911, 7941, 7961, 7970, and 7971 that are running SIP have the capability of supporting multiple lines with the same directory number in different partitions. However, configuring and using other phones that are running SIP with multiple lines with the same directory number is not supported.

•If the number of shared-line users in the conference is equal to or greater than the configuration for the Maximum Number of Calls setting for the device from which you are attempting to barge, the phone displays the message, Error Past Limit.
