I have been using a Linksys SPA 962 with the 3CX system and Broadvoice as the provider for awhile now. I'm having this strange issue now though where I can make outgoing calls just fine, but if someone calls in and 3CX routes the calls to my phone it will have a very short "half-ring" of sorts and send the call to voicemail. It will show a missed call on the screen, but it sends the call to voicemail so fast that it's impossible to pick up the call. Has anyone else encountered this issue? I've tried a variety of things such as changing the "busy detection mechanism", going over the config laid out on the 3cx website, and rebooting the phone and server. Any other ideas on why this is happening?
