Troubleshooting
Registration failed: Double-check your username and password. Cloudflare or VPNs can sometimes block the connection — try switching to mobile data to test.
No audio on calls: Go to Zoiper Settings → Audio. Ensure that uLaw (G.711u) and aLaw (G.711a) are the top enabled codecs.
Transport issues: If UDP is blocked on your network, go to Account Settings → Network and switch the transport type to TCP or TLS.
One-way audio: Enable STUN in the network settings to help with NAT traversal.
