Yealink T58 Phone

Issue: When on a call for longer than 20 minutes one way audio occurs. It will happen exactly at the 20 minute mark. I can hear the caller the caller cannot hear me. We have re-produced this problem on another T58a phone also.

We have tried a Audiocode C450HD, MS Teams client and the issue does not happen at the 20 min mark.

Tried updating to the 58.15.0.26 firmware and still have the same issue.
