When i try to integrate Expressway-C and E with CUCM 8.6.2 as proxy for Mobile Remote Access (Not SIP Trunk), I receive this error "not supported version". I know that Expressway only working with CUCM 9.1.2 and later. But my question is:
- Why Expressway not supported CUCM 8.6 and older with MRA function (not SIP Trunk), not all customer have a condition to upgrade to 9.1.2 and later. Older system cannot use this function, it is very deficient of Cisco.
- What is difference between CUCM 8.6 and older with 9.1.2 and later that make Expressway does not work with 8.6.2 ?
Customer is very excited in Collaboration Edge Solution but when talk about this limit, they are not happy about that. Any solution for this trouble ?
