Suddenly I am unable to receive any inbound calls. What is the cause?
The inability to receive inbound calls is directly related to the Phone Adapter’s ability to register with our proxy server. If the Phone Adapter is not registered, the DigiPhone proxy server will be unable to route calls to the device. When a call is unable to reach the phone adapter, DigiPhone will route the call to your voicemail (if you have the SSP option).
