MX64 and MS PSTN Teams Voice Service 1 way Audio

Any one having issues with one way audio using MS teams to PSTN network with MX64 ?

 

I have a number of customers using TEAMS voice to the PSTN network.

 

If you dont make any calls for a while when you make the call you get 1 way audio  Called party can not hear the calling party.

 

You hang up and then call again and it works.  and keeps working till you  don't make calls for a while (say 30 minutes)

 

customer are now ringing there mobiles first before ringing person so they know it will work.

 

if I remove the meraki and put in a cisco router running NAT  it works fine..

 

It is like something gets setup on first calls and then stays there and then times out after no use...

 

tried a sip phone via MX and it works fine.   just seems to effect MS Teams

 

Any one else seeing this ??

Kind of a big deal

We use Microsoft teams with a SIP provider for PSTN access for both ourselves and our customers.

 

We have zero issues.  It's a dream.
