Connect-it Services – Network Configuration Guide

Version 1 – June 25

This guide is designed for administrators who need to make changes to the configuration of their network to enable Connect-it services.

Background

This guide details the required ports and settings to enable Connect-it-powered devices and services to successfully register, place calls, and retrieve configuration files when operating behind a customer firewall. It also includes the IP addresses and ports needed for third-party application integrations.

Firewalls

There are many types of firewalls and network devices available. While it’s not possible to cover every configuration, the tables below list the required ports, FQDNs, and IP ranges needed for standard functionality.

We recommend consulting your network administrator before applying these settings to avoid disruption to other services.

SIP ALG (Application Layer Gateway)

SIP ALG is a firewall/router feature intended to assist SIP traffic, but in practice it often interferes with:

  • Device registration

  • Call transfer, pickup, and conferencing

  • Audio quality (one-way or dropped audio)

Because SIP ALG modifies SIP headers and SDP content, it should be disabled on all devices. Refer to your vendor documentation or the Connect-it support portal for instructions on disabling SIP ALG.

Pre-Requisites

The following IP addresses, FQDNs, and ports must be allowed through your firewall for all Connect-it services to function correctly.
