CME 4.1(0) and IOS 12.4(15)T1 on 2851.
Also tried with CME 4.2 and 12.4(11)XW1, same problem.
Call Transfer with full-consult is not working with internal or external calls.
If I configured full-consult, I can consultate the second DN (now original caller is on hold, second dn is connected, but after pressing transfer or hangig up the phone, both lines are in status on hold and I will get hold-alert notifications and message transfer not possible on the phone with both lines on hold.
Original callers phones shows ring out, the phone (dn) which should be transfered to shows connected.
There is also no music on hold heard.
Phones are 7961G-GE and 7941G-GE. Firmware 8.2.2SR1S. We have also tried 7.03.
If we use local-consult as workaround, consultative transfer does fail sometimes.
