I have an Unified Communication Manager v4.2 installed and I want to buy the Cisco IPIVR software. Can you please tell me what version of IPIVR I need that would be compatible with UCM4.2 ?
Also do I need to purchase any other software besides IPIVR?
From the IPCC matrix, the following IPIVR version are compatible with 4.2(3) and 4.2(1):
The compatibility matrix list these version of IP/IVR as being compatible with the CUCM 4.2 - 3.3(4), 4.0(3) and 4.0(4)
Other software would depend on what you are looking to accomplish.
The CRS compatibility matrix is here:
