I am using openvpn certificate and I can to register extension on other server with one IP address on VPN network,but, if I want to register one account on other server into my LAN network or internet it doesn’t work.

Please add below parameters in the configuration:

sip.listen_in_peer_localip.enable=0

account.x.vpn_address_take_precedence= （0 or 1）

0 for local IP;1 for VPN IP
For example：

If you want to register account 1 in the server  via VPN, you need to add:
account.1.vpn_address_take_precedence=1
if you want to register account 2 in the local server ,you need to add:
account.2.vpn_address_take_precedence=0
