CRS refers to the base application engine that both IP IVR & IPCC Express are built on. So applications like Call Manager Extended Services, IPCC Express, IP Queue Manager & IP IVR are all built on top of the CRS Engine.
As I noted IPCC Express is an ACD application that uses CRS as its base engine for call processing, queuing, call control, etc. However, IPCC or IPCC Enterprise is a call center solution that consists of the Cisco ICM product as its core call control engine.
IPCC Enterprise consists of the ICM, Call Manager, a CTI desktop & a queuing platforn like IP IVR all integrated to create a call center application.
The major difference between the two IPCC products is architechture and scalability. IPCC Express scales to 300 agents while IPCC Enterprize can scale to ~ 6000 agents.
There are three versions of IPCC Express:
IPCC Express Standard is a basic ACD package that provides basic queuing, prompt and collect and announcemnts.
Thanks guys. I've installed CRS 3.5(4) on the same server as CCM 4.1(3). Does this mean I can't do anything with it until I install an application such as auto attendant, IPCC express, IP IVR. (Is IPCC express also an IP IVR?)
Are any applications installed as part of the CRS?
