Looking to see if anyone can assist or has thoughts on Microsoft Teams Voice using AudioCodes M800B to push our numbers coming from our CentryLink PRI to teams. The issue I am having is Degraded Audio on the recipients side, sporadically there will be points in a call where the recipient looses audio for a second or 2. CenturyLink is only a best effort network but our 500mb pipe isn't even hitting about half that and at max we maybe have 10 users on the phone at once. When I look at the calls in teams a large majority looks like they are good but there are about 5% of calls the come back with a 408 and 504 Response code.
I have made sure on my Meraki network I have set up all QOS and I have tried to trouble shoot with AudioCodes, Microsoft, and CenturyLink but so far no luck... my company has invested a large amount of time and money and I have about exhausted all my resources trying to track this down... any thoughts that may help me resolve this would be great;ly appreciated.
