Our Customer have a solution IP Telephony with CallManager 4.1.3 with configuration Attendant Console. In this morning my Customer have 05 branches and the call function Ok. In the evening our customer have only branch that is associated with service 0800. A First call is receiving normaly, but the second call in the branch go awaiting and the user not perceive that have the second call. This behavior is normal when using the Attendant Console because when we don't have Attendant Console we can configure the IP Phone for to attendant 02 call or more depend of model.
