only one Application shall use OpenVPN

We want to use Zoiper (VoIP) on Android and have configured an OpenVPN connection on our smartphones. Everything is ok and we can use VoIP with Zoiper that connects to our PBX.
But OpenVPN cuts down all Intenet connections.
Can we restrict the OpenVPN usage to one application on Android (Zoiper) or is there another option to use Internet parallel to OpenVPN?

Oops, no answer from nobody after 10 days?
Does nobody know the answer or is this the wrong thread?

Hello ERM-Consulting,

OpenVPN can break Internet connectivity if things are not configured properly. Normally with a split-tunnel configuration, the Internet access is left totally untouched on the device, and only specific subnets are routed through the VPN tunnel. My guess would be that you're maybe pushing a DNS server that just doesn't work for Internet addresses, and thereby could possibly break things.

Without more details it'll be hard to determine what exactly breaks. Perhaps it is best to post log details at https://openvpn.net/support so we can analyze that without having to post such details on a public forum.

Kind regards,
Johan
