All of a sudden, I'm having an issue with my IP Phone.. It connects to my PBX and can make incoming and outgoing calls. I have the 3CX client for windows on my laptop, and I also have the app on my iphone... Once I go to the App on my iphone, my IP phone goes into no service. When I go into the WebGui and see the status it says Contact Mismatch Error. I reboot the Phone, If the App is still on, I get this same error. If the App is off, phone boots right up, but as soon as I go into the app, get the same thing. I do not get this error on the 3CX client for windows on my laptop, just the app on my iphone. I uninstalled the app from the iPhone. I did another send e-mail of the config files, and still the same thing. I never has this issue before, and now all of a sudden, I am. There was nothing that has changed since the config and provision of these 2..
