I have recently installed a Mitel MiVB for a customer who has 7 Soundstation IP 5000 conference units and wanted to keep them on the new system.
I defaulted all the settings on the units and configured the new settings for the Mitel.
Customer is complaining that the sound quality is not very good and I am at a loss as to what it could be.
I have configured the phones as per the Polycom/Mitel interop document (SIP CoE 10-4940-00113)
There seems to be a few questions and answers with other Polycom conf phones regarding codecs and priority, not sure if this is connected or not but would just like some confirmation.
Also is there a specific firmware version for Mitel, or should I just upgrade to the latest version?
The units have Firmware 4.0.10.0689 installed and I can see that the latest is 188.8.131.528
Any help greatly appreciated

Are these internal or external calls or both?
The calls are both ways.
The customer is saying that unless they place themselves directly in front of one of the units arms then the sound is muffled.
Not sure why it would make any differenece tbh?
I have upgrdaed one of the units to the latest and asked the customer to retest and see if it has improved things, I am waiting for a response
