Certified SIP Trunks for 3CX Phone System

What are SIP Trunks?

A SIP trunk is the modern day equivalent of a T1 trunk. Where in the past you would buy a T1 trunk from a Telco provider and connect it to your legacy PBX, today you can buy a SIP trunk from an ITSP (Internet Telephony Service Provider) and connect it to your VoIP/IP PBX. SIP trunks use the SIP standard. The name ‘trunk’ comes from the telecom world and it means, more or less, a group of phone lines.

Using this standard protocol, telecom service (VoIP) providers connect one or more channels to the customer’s PBX. Phone numbers and DIDs are linked to the SIP trunk.

Benefits of SIP Trunks

Lower Monthly Cost

The monthly cost to have a number of lines installed at your office drops significantly with SIP Trunks.

Moving? No Problem

SIP Trunks are not bound to a location, so it’s easy to move without having to change your company documents, phone numbers, etc.

Better Customer Service

Provide better customer service by adding more geographical numbers. Quickly and easily add numbers to your SIP Trunk and terminate them on your IP PBX, giving your customers more options to dial in at a significantly lower cost. Customers can contact you more easily and sales can increase.


It is easy to add channels to your SIP Trunk to handle an increase in calls. A simple phone call will allow you to add channels. Compare that to the delay in having additional lines installed, having to upgrade your old PBX to handle more lines and all the additional costs associated with the upgrade.

Eliminate Hardware

SIP Trunks will eliminate the need to buy and manage VoIP Gateways. All phone calls come in through your internet. No extra conversion often means better quality too.
