I simply forgot MWI wasn’t working since I get an email and just delete the message via email after listening! My daughter asked me why she never knows if she has a voicemail (she doesnt have usable email) and it prompted me to fix it. I’ll post what I did and how I did it shortly. Since call manager doesn’t inherently support authenticated sip trunks of course, no google voice integration, i’ve used my Asterisk server (running since 2002) as my Gateway for sometime. When I got my hands on a few 88xx, 8945s, and a dx650, I decided to setup call manager. To keep everything smooth, I just send everything to Asterisk and let it route to the cloud. Asterisk also provides my voicemail capability for the asterisk phones (my parents, a few military friends, and a few friends who would like to call locally within the US) and the Cisco phones. Calling into voicemail and diverting calls to voicemail is extremely basic so I won’t discuss this at all, but MWI stumped me. Asterisk handles MWI pretty differently from Unity Connection and I struggled with it for a bit. After an hour of internal server errors I decided to try scripting.
