Frequently Asked Questions

SIP trunking connects your PBX (phone system) to the public telephone network over the internet. Instead of traditional phone lines, SIP trunks use your internet connection, providing significant cost savings, scalability, and flexibility.

Use IP authentication - add our SIP server 34.23.59.14 or hostname s1.ipcomms.net to your trunk config. Ports: 5060 (UDP/TCP) or 5061 (TLS). No username/password needed - just whitelist your IP in the portal.
