Hi All,
I have strange issue. Shortly about scenario:
I have a branch office with two users. User A and user B - both with same configuration. User A has NO issues - everything works fine. User B cannot establish call with users who are connected via VPN - error message is "Call ended due to a network issue". Again user A no issue. If user B sign in to Lync on computer of user A and try to call to the same user on VPN it is still not working. There are no error messages on Edge and FE and also nothing blocked by firewall.
Any advice please?
