I have installed a Summit 80 for my customer with the UCS Mobile client. It all works good for a day or so, then stops. When I say stops, I have it programmed to ring on incoming calls, it works for a random amount of time, then stops ringing on incoming calls again. The app is on an iPhone. I have checked the settings in his phone the best I can and can't find anything wrong. Do you guys know of anything I can look for? When I go to his location, I don't really do anything to the phone and it starts working. On a similar note, he has some IST cordless phones. He is telling me that they stop ringing from time to time also. He is not sure if they both stop at the same time or not. There again, when I get there, they ring.
