FAQ
Integration questions

My platform is not listed. Will it work?
Any platform that supports standard SIP trunks works. Use the connection details on this page; the Asterisk guide is a good reference for the settings most switches need.
Should I use IP or credential authentication?
Use IP authentication for servers with a static public IP, such as dialers and PBXs in a data center. Use registration for softphones, dynamic IPs or when several sites share one account.
What number format should I send?
Send the full international number as country code plus national number, without + or 00. Every guide shows how to strip a local prefix before the call reaches us.
Why are my calls rejected with 403?
Either the source IP or credentials do not match an endpoint, or the caller ID is not authorised on your account. Both are checked in the portal.
Can I connect several platforms to one account?
Yes. Create one endpoint per platform or site in the portal so channel limits, caller IDs and CDRs stay separate.
