SIP Peering
Enables a direct trusted IP - IP network connection between your IP-PBX and our voice public IP via a static WAN IP address.
Recommended settings
Proxy: 27.111.12.66 (27.111.12.0/24)
Recommended Firewall rule: 27.111.12.0/24.

We support the following two variations of Peering:
Global SIP Peering: where all numbers on an account are directed to a single customer IP address
Standalone: where a customer only wants to direct calls to a single number to a standalone IP address
Trunking: supports customers with on-premise PBX devices that connect via device registration (UserName and Password). This feature allows an administrator to configure a single registration number to their PBX but preserving the CLI of all outgoing numbers.
