No voice , when VPN connection is turned on

[m-shirokov]

Hi,
there is a problem with voice call , when VPN application (we use Cisco Anyconnect, but the client product doesn't matter here) is turned on

We've done some research about this problem.

When both users are in WAN mobile connection - everything is fine , both can hear each other
Here is some traffik logging:
1306 36.182676108 192.168.1.155 1.1.1.1 STUN 174 Send Indication XOR-PEER-ADDRESS: 2.2.2.2:41552
So , XOR-PEER-ADDRESS: 2.2.2.2:41552 is the WAN address of the client's mobile provider

When one of two callers turns on the VPN app , the behavior changes:
XOR-PEER-ADDRESS: 192.168.0.101:55352
XOR-PEER-ADDRESS changes to the address , that have been assigned to VPN adapter
and voice is no longer heard durng the call

Maybe , it is possible to add a setting so you can choose an interface for XOR-PEER-ADDRESS ?

Thank you!
