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.

Thanks,
Lawrence

Working on the same. Have you had any luck?
