Hi,
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 4.0.14.1388
Any help greatly appreciated
