Setting up SIP Peering

SIP Peering (also known as SIP Trunking or Call Paths) allows you to statically connect your IP-PBX to our public SIP proxy 27.111.12.66.

⚠️ : Note

Peering is different from SIP Registration. Registration requires a Proxy address (plus.2talk.com) UserName and Password to authenticate with our voice proxy. Peering instead relies on your fixed WAN IP address.

Once SIP Peering is enabled, your WAN IP is whitelisted and all other IPs are blocked from accessing our voice service.

As an extra security measure, we strongly recommend creating a firewall rule that restricts SIP traffic on your PBX to our IP range:

27.111.12.0/24

We support three modes of Peering:

1. SIP Peering Global

2. SIP Peering Standalone

3. Trunking

1. SIP Peer Global

Global Peering routes all Inbound and Outbound traffic on an account to a single nominated WAN IP linked to one phone number.

• All CloudPBX features are disabled in this mode (except for emergency failover).

  
  

• Select SIP Peering Global.

• Add Primary Trunk Host IP Address, and fail over Trunk IP Address (optional).

• Select Save.

2. Standalone Peering

A standalone peer is where the network admin connects an IP-PBX to a single number. Standalone peering is a convenient mechanism enabling administrators to connect multiple offices each with its own WAN IP.

1. Select Line SIP Peering Standalone >> Enable

2. Add IP Address.

3. Select Save.
