Calls are not working for office users|| After implementing LBR

Rohit Mahajan 0

We have a very simple setup for Microsoft Teams direct routing. Everything is working fine with incoming and outgoing calls.

We are facing problems after implementing LBR. I am stating a problem as it is with respect to the setup we have.

We have users who are sitting in the office , using team applications on their PCs and able to make and receive calls.

Now we have implemented LBR to restrict these users to make calls when they are not connected to the office network or restrict when they are trying to make calls from any network except the office.

Now in the office the private network is 192.168/168.0/24 and trusted public ip's are also correctly defined

I have defined the private subnet in the network topology subnet And public IP's in the trusted IPs list.. So , ideally the call should work when users are trying from the office network. But the problem is calls are not working even from the office network which is allowed as per the LBR. ** Users are getting error : calls failing with Get Outbound Direct routing - no trunk config found by LBR selection criteria.

Here is some more information :



1)  Below logs   confirm LBR is configured correctly:

        "_comment": "Used to find emergency address,against Tenant Location Network Information (LIS), otherwise against Client Geo Location Information (CLS) if available"
      }                : I believe this does not apply here as we are not dialing any emergency numbers

Call is failing with below cause code:
