Grandstream DP 715 had worked just fine but now I can only make outgoing calls.
Incoming calls does not work properly, except on an erratic basis, but 99% of the time, the device won't ring and there is no call. I took out the battery and unplugged the base to do a complete reboot and reset Registration
The Grandstream DP 715 is a portable device. Any ideas would be most welcome!
