Rockwell ACD dead air calls Rockwell ACD dead air calls RGarcia87 (TechnicalUser) (OP) 19 Jun 13 09:52 Does anyone know what may cause a "dead-air" call? Our agents receive calls once in a while where they don't hear anyone. They see the DNIS number on the phone display but don't hear the caller.

Also those are DS1 or ISDN PRI?
