Dear sir, My customer report a conference issue to us: They can not use conference bridge successful under some conditions. Our testing as below:
1. I use Cisco communicator to register to their call manager successful, when I tried to make a call to a cell number, it is successful.
2. Then I press the conf softkey to 2nd call, the first call to cell was dropped suddenly.I check the cisco communicator,it shown "CM down, features disabled",and it still shown the connection to first call (cell)still count,even if the call already dropped.
How should I need to check? Thanks.
