I gonna establish an IVR which allows the callers to opt to transfer their calls to a call centre. In case the call centre’s line is occupied, the calls will be placed in a queue.
I’ve the following questions:
1. Is call queue an intrinsic featue of IVR or ACD?
2. I heard that ACD is not supported by Centrex. Then how about PBX? Is ACD supported by all PBX?
Could someone help?
