MiVoice Office 250/Mitel 5000 / How to troubleshoot audio quality issue (sounds muffled)?

« on: May 06, 2022, 01:26:17 PM »

Hi all, we have a Mitel MiVoice 250 system with 5320e IP phones, lately some users complained about the audio quality, it sounds muffled and they cannot hear well what the other party is saying in meetings.  We did the phone system reboots, switching IP phones (to new ones), but problem persists.

I'm pretty new to the phone system area... Any suggestions what to look at or where to start?
Also, is there any related Mitel installation/training course available online?  (I searched Youtube but the most relevant i could find were some Mitel programming videos from a channel named DenwaUK).  Thanks.
