Troubleshooting

If a call does not connect

403 Forbidden

Your IP is not on the allow-list. Send us your current public IP.

404 or 503

Check the dial format, destination and available balance on your account.

One-way audio

Check NAT and firewall settings and that RTP ports are open between your switch and ours.
