Registration and Peering Explained

SIP Registration

We support most SIP-based VoIP devices, including Analogue Telephone Adaptors (ATA), IP phones, IP PBX systems, softphones, and third-party services.

Generic SIP registration settings

• Display Name: Your caller ID.

• User name / Account ID / Authenticate ID: The phone number you are registering (e.g. 61xxxxxxxxxx).
• Password: Your number’s password.
• Transport: UDP 5060 / TLS 5061
• Server Expires: 180
• Register with the Proxy: Yes
• Make calls without registration: No
• Codecs: G711a/u, G729

SIP Peering

SIP Peering enables a direct trusted IP-to-IP network connection between your IP PBX and our voice network via a static WAN IP address.

Recommended settings

• Proxy: 103.55.116.65 (103.55.116.0/24)
• Recommended Firewall rule: 103.55.116.0/24
• Ports: UDP 5060 or TLS 5061

Peering modes

We support three variations of SIP Peering:

• Global SIP Peering: All numbers on an account are directed to a single customer IP address.
• Standalone: A single number is directed to a standalone IP address.
• Trunking: Supports on-premises PBX devices connecting via device registration (username and password). Allows administrators to configure a single registration number to their PBX whilst preserving the CLI of all outgoing numbers.
