Customer has a CIX 100 with LVMU voicemail. They have a small 2 person department that works completely remotely. Never worked on site, never will. They'd like an option off of the auto attendant that will call 2 cell phones at the same time. 1 cell phone is easy. 2 I think will be impossible without the simultaneous ring FeatureFelx application. The only way around this I can think of is to use a 3rd party service like Google Voice and have the LVMU transfer the call to one single external number. This isn't ideal and I'd rather the CIX handle this itself.

Anyone have any magic they know that will cause this to work?

Use the copy to function in the mailbox and let the 2nd mailbox call the other user. Note this will use 2 of the voicemail ports while doing the calls
