Hi,
I have a 2951 ISR running Unified Commnuications Manager Express (8.6). IP telephony runs perfectly and alll 150 handsets work without an issue. We are now trying to improve the system by adding Voicemail capability for some users, this has been done by installing an ISM-SRE-300-K9 module with the correct sotfware installed.
Using the Configuration Professional the module has been addresses and the sotware activated via the Wizard. However, I am unable to configure the voice mail service as I am presented with an error saying "Cisco Unity Express module is installed with CUCM call agent which isnt supported. Cisco Unity Express module features will not be available."
I am unsure how to resolve this. Could someone please help.
Thanks,
