Help with Cisco CallManager/Asterisk

I’ve been fighting with integrating Asterisk and Cisco CallManager for the past week. Initially, I am just trying to use Asterisk as a voicemail server for our CallManager. However, after following several guides, I am unable to get it to work. All of the guides are missing some information. If anyone has a setup like this working correctly, could you please message me? I have the SIP trunk working and calls are transferred to Asterisk voicemail, but the RDNIS doesn’t seem to be working.


Working on the same. Have you had any luck?
