7945 Shared line appearance

[balitewiczp]

Hello. Im trying to create a very crude paging system.  If I create a shared line appearance as the 2nd line on a host of phones, and then set that line to auto answer with speakerphone.   I then create a Hunt Pilot and Hunt List, and Line Group with this 2nd line number and the distribution algorithm set to Broadcast.

As long as I dial the Hunt Pilot number, I cant see why this wouldnt work.

any thoughts are appreciated.

Hey Pete,

The problem here is that you can't enable Auto Answer

on a shared line

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.

Ok, so the limiting factor is the shared line.  What Im thinking now to create virtual non DID extensions in a seperate partition, and use those virtual numbers as the line group members.

That should take care of the shared line

[Jaime Valencia]

That still won't work, even if you have different DNs in the line group, only one can answer the call.

Save your breath, a lot have tried before you, and there's NO way to do paging with CUCM.

Your options are either upgrade to CUCM 9.1 which now comes with SingleWire or buy a separate paging solution.
