Having an issue where after appox 10 min on a call the user loses audio. The caller still hears them but no receive audio. User cranks up the volume and gets bad echo but still no receive audio.
I tried jiggling the EHS cable at the base and was able to duplicate it right away. Any known issues with this plantronics series and NEC?

Cable is lose or bad?

Yeah that's what I'm thinking. I have 3 other EHS's that don't have this issue.
