ZoiPer does not register on VPN

0 votes


ZoiPer does not register on a network change. Is it possible to get a sip trace of the Android client?

Here are the steps when it refuses to register:

1. Wifi connected - ZoiPer is registered

2. Start VPN - Network is changed

3. Zoiper refuses to register and gives 408 timeout. CsipSimple however registers fine with the same credentials

I'm having the same issue with NordVPN. Connects fine without VPN, but as soon as i turn on VPN, Zooper fails to register with error 408.

I've tried disabling STUN but that made no difference.

Please disable STUN from the Network settings menu in the account configuration.
