Grandstream DP750 Ringing Stopped Working. What Can I Do?

Q: I have a handful of Grandstream DP750 with headsets at different customer sites and they all experience similar inbound call issues. The most common is that the phones will work fine inbound and outbound after a reboot but within a few minutes inbound ringing stops working but outbound calls work fine. Please advise.

A: Try factory reset the phone after the firmware upgrade and re-register the handset to the base station. It should solve your issues. Here is the DP750/DP720 Firmware Release Note for your reference: http://firmware.grandstream.com/Release_Note_DP750_DP720_1.0.2.16.pdf
