Trunks
Manage and configure SIP trunks for connecting the Cloud PBX with external media servers. Read here how to create, test, and assign trunks to routing rules.
A SIP Trunk is a connection to another media server that supports the SIP protocol. We create trunks between the Cloud PBX and an outside provider, PBX, or POP.
After creating trunks, you can use them in dialing rules for a specific country, user group, or lead.
Managing Existing Trunks
You can find trunks in Settings > Outbound Configurations on the Trunks tab.
