We are operating on version of Cisco Call Manager 4.1(3).
Cisco CallManager System Version 4.1(3)
Cisco CallManager Administration Version 4.1 (0.11)
Cisco CallManager Serviceability Version 4.0 (0.1)
We have a one Cluster set up - Publisher and Subscriber at our Head Office and various remote branches via a 2mb MPLS VPN (low utilisation with qos enabled). Phone types are 7940 and 7960.
At one of our remote branches we cannot pick up an incoming external (using Pickup function on a third phone) call if it has been transferred using the Transfer, key in extension number and then transfer again.
1) Ext 1011 receives an external call and transfers it to Ext 1012 using the above transfer method.
2) Ext 1013 cannot Pickup the call using the pickup function.
Ext 1013 can Pickup the call if:-
1) If the external call to 1011 has diverted on busy to 1012
2) If the call is internal ie Ext 1010 calls 1011, 1011 lifts the handset and transfers the call to 1012
3) Ext 1011 receives an external call and transfers it to Ext 1012 which is busy and so hunts to 1014
I know this is a late answer, but for those who need to fix the 4.1 pickup issue quickly (w/out patch or upgrade) for a small amount of users; the best remedy is to create a new pickup number, then reassign the problem DNs to the new number. Don't forget to delete the old pickup number.
