Transcoding issue on the Audiocodes Mediant

I have had a issue with a customer where we have implemented Direct Routing. It’s a HA setup version 7.20A.260.095 running virtual on a VMware cluster.

The alarm says: License Pool Alarm. Some of the license pool allocations exceed maximum capability and will not be applied.

In the syslog i see the followig errors show up:

            20:11:35.145  172.20.1.1  local0.warn    [S=3603724] [SID=815d0e:57:143476]  (N  3305189)!! [ERROR] ResourceCounter: Cannot allocate more Media channel [0/0] [Time:23-11@20:11:36.770]

When i look in to my license i have transcoding assigned by the OVOC, but they are not allocated:

Direct Routing keeps sending Anonymous

Problem

While i was configuring an Audiocdes SBC with Direct Routing setup and started testing, we faced the issue that every call outgoing is presenting Anonymous as caller ID.

When looking up the SDP invite i saw the parameter Privacy showing up.

Solution

After some digging, i found that the Privacy ID is added automatically when you enable the option -forwardPAI $true (P-Asserted-Identity) within the Set-CsOnlinePSTNGateway cmdlet.
