SIP Trunking Feature

Gateway Configuration

A gateway is the specific endpoint calls are sent to or accepted from. Managing gateways as first-class configuration - created, listed and removed independently of the trunk - means changing where traffic goes is an edit rather than a re-provisioning exercise. That is what makes it practical to keep a secondary path configured before you need it.

What Gateways gives you

Define the gateways your calls traverse, and keep several configured so a route is a configuration change rather than a rebuild.

Gateways are independent objects

Add or remove a gateway without disturbing the trunk or the carrier it belongs to.

Keep an alternate path configured

A second gateway can exist before you need it, rather than being built under pressure.

Separate inbound and outbound paths

Different gateways for different directions or destinations where your setup calls for it.

Listed and auditable

See every configured gateway rather than discovering one nobody documented.

How Gateways works

End to end, in the order it actually happens.

  1. 1

    Create a gateway with its connection details.

  2. 2

    Associate it with the relevant carrier.

  3. 3

    Send test traffic through it.

  4. 4

    Keep or remove it as your routing changes.

What Gateways does not do

Worth knowing before you build a process around it.

  • Configuring a gateway does not by itself provide automatic failover. Treat failover behaviour as something to design and test, not assume.
  • The gateway must be reachable and accept your traffic - configuration on this side does not fix a refusal on the other.

Common uses

  • Multi-carrier routing

  • Regional call routing

  • Preparing a secondary path

  • Migrating between providers

What is SIP trunking?

SIP trunking is a method of delivering voice calls over the internet using the Session Initiation Protocol (SIP). It replaces traditional PRI/ISDN lines, connecting your PBX or contact center to the public telephone network (PSTN) via an internet connection.

How is SIP trunking different from PRI?

SIP trunking uses internet connectivity instead of physical copper lines. It offers elastic capacity (add or remove channels instantly), lower cost per minute, geographic flexibility, and no need for on-premise telco equipment. PRI lines are fixed at 30 channels and require hardware installation.
