Still watching to make sure. Was going to go after customers before the migration happened but now going to wait a few more months to see how stability goes. The migration has seemed to fix a longstanding Cisco SPA phone 5 second static delay on outgoing PBX calls that I knew was on their end. Sure enough was on their end. I spent so much time with Cisco trying to resolve it and they said it was a problem with their PBX config that finally disappeared after migration. If only I had not lost so many customers from PBX stability and that particular issue. Maybe it will finally be a good solution because I was about to give up.
