System has been working for over a year. Not sure what changed but now, on most incoming calls the caller cannot hear us when we answer the phone. Some calls get through. Outgoing calls audio is good both ways.

Title: No audio on incoming calls
Issue Type: Software
Description: About 20 GXP2160 on the 220.127.116.11 firmware.
Grandstream has been silent despite my repeated requests so I am looking at the community for a little help. I would appreciate if some one can tell me what I should be checking.
