Registration and Peering explained


SIP Registration

We support most SIP-based VoIP devices including Analog Telephone Adaptors (ATA), IP Phones, IP PBX systems, and Softphones.


Generic SIP Registration 


  • Display Name: your caller ID

  • Proxy Server: call.sipcity.com.au

  • User name / Account ID / Authenticate ID: (the phone number you are trying to register 61xx)

  • Password: your number's password

  • Transport: UDP 506 / TLS 5061

  • Server Expires: 180

  • Register with the Proxy: yes

  • Make calls without registration: no

  • Codecs: G711a/u, G729


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: 103.55.116.65 (103.55.116.0/24)

  • Recommended Firewall rule: 103.55.116.0/24.

  • Ports: UDP 5060 or TLS 5061 


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.
