We have recently replaced Group 500 codecs with the new G7500. At the same time, in order to be able to use microphones from Group 500, we bought a Microphone IP adapters .
Faced a problem. Audio loop. Sound loop. That is, remote participants hear themselves with a slight delay.
After installing the codec and adapter (or resetting them to factory settings), the problem is absent for the first time. But if the codec is left for some time in the call (presumably 1 hour), then an audio loop appears. In subsequent calls, this problem appears with start
If you physically disconnect the microphone from the adapter, the audio loop still remains!!! (It is clear that local participants cannot be heard.)
The audio loop disappears if we disconnect the adapter from the codec or mute the sound
Only the microphone adapter is connected to the codec (no new IP microphones are used)
Current version of the codec 3.4.0-292042
Current version of the Microphone IP Adapter 220.127.116.110133
The codec SN 8G210450363CF2
