What is a SIP Trunk in Kiwi VoIP?

A SIP Trunk allows you to route multiple calls over the internet from Kiwi VoIP directly to your SIP-capable PBX or voice platform. It's ideal for businesses running their own phone systems that need reliable, scalable connectivity with modern VoIP infrastructure.

🔗 What You Need
To use a SIP Trunk with Kiwi VoIP, you must have:

✅ A SIP-capable IP PBX
✅ Or a VoIP Gateway or SIP/ISDN Gateway

🚫 If you don’t use one of the above, a SIP Trunk is not the right option. Consider using Kiwi VoIP Cloud PBX features instead.
