Registration and Peering explained

SIP Registration

“Registration” is used to connect IP phones and some IP-PBX machines to our hosted cloud PBX using a UserName and Password to authenticate access.

Required Settings

  • UserName: [phone number] eg 13106341870
  • Password: account or line
  • Proxy: plus.2talk.com
  • Transport: TLS Port: 5061

SIP Peering

Enables a direct trusted network-to-network connection between your IP-PBX and our voice public IP. The main advantage of Peering is greater flexibility of number routing within your onsite-PBX. To use Peering you will require a static WAN IP address.

We support the following two variations of Peering:

  • Global SIP Peering: were 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.
