SIP Trunking is a service that allows you to connect via Session Initiation Protocol to an Internet Telephony Service Provider’s network. In simple terms, this means that you can use this service to send and receive phone calls across the internet.
The trunk or connection to the provider’s network can be tailored to your specific needs.
It can have a limit on the number of calls that can be made at the same time. This is generally known as channel usage and this forms the basis of how the service is billed. Each channel is charged at a cost per month. What differs from traditional telephony is the ability to increase and decrease this without having the penalty of always paying for the highest amount. The service can be set up to allow for national calls only, or for national and international together, in fact, you can choose to either allow or disallow calls to any worldwide destination.
By utilising your existing PBX or IP infrastructure and purchasing the small amount of equipment required, companies can save over 40% on their legacy business telephony system.
SIP trunks can be created on the day and can be deployed by the client in a very short timescale, as opposed to traditional analogue and digital solutions, which can take anything from seven days to multiple months.
Remove the restriction of being tied to your local exchange area and the numbers that are provided within that area. You can have numbers from London, Birmingham or Manchester all sent to your office located anywhere in the country.
Choose your own IP PBX. Our service is proven to work on most popular IP PBX models via our simple registration method.
Pay for how many concurrent calls your business requires, not how many extensions.
After being introduced by a 3rd party several years ago, we've been delighted with Packnet and I can say quite definitively that their reseller platform is simply the best 3rd party product we use across our entire managed services portfolio.

After being at the mercy of a different VoIP supplier for a number of years, Packnet are a breath of fresh air. We've been a customer of Packnet's for 6 years now and would not think about looking anywhere else. The service has been rock solid from day one.

I have known Packnet for roughly ten years now and the service has always been second to none. The service everyone there gives is outstanding and the guys (and Holly) are so knowledgeable.
- Eddy Leonard, Director, EDI Communications
The contract we signed is a rolling 30 day contract which speaks volumes, you don't build a business offering contracts like this without rock solid customer service. Highly recommended!

The whole experience with Packnet has been brilliant. We have been using Packnet's Metis phone system for over 8 years now. In that time it has been ultra-reliable.

Earlier today we had major issues with two of our Gigaset handsets & the base unit. We would like to take this opportunity to formally congratulate you on your easy to use support system and the excellent representatives who picked up our support call. Credit where credit is due.
- Don Wall, Senior Infrastructure Engineer, Bioxydyn
I have been using your service since I took over from a colleague in January and the VoIP system was a little daunting at first. Your team have always done an excellent job of providing support however, I consistently get fast responses to my problems and high-quality support and feel much more comfortable with the system as a result. This is the best support I have ever received.
- James Campbell, IT Support Analyst, Applearn
Great service, great support, the 2 important parts of any technical service delivery. I highly recommend Packnet.
- Roy Wilding, Creative Director, PushOn
Our company changed over to Packnet 2 years ago after being with a company that were a nightmare to get through to on the phone and deal with. Since we have been with Packnet we have had a different experience altogether, the team members are so helpful, they listen and deliver the results. I would not hesitate to recommend Packnet.

SIP (Session Initiation Protocol) trunking refers to a VoIP service that allows a business to connect their current PBX system to a cloud-based phone system using an ITSP (internet telephony service provider) such as us.
What does PBX stand for? Private Branch Exchange (PBX) is a private telephone system used within an organisation. It allows users within the organisation to manage incoming and outgoing phone calls. How a PBX telephone system works In a PBX phone system, users will share a certain number of outside lines, these lines are used […]
Thanks to SIP being a standardised technology, compatible PBXs are not hard to come by. If a PBX, or phone, or hosted system, is SIP compatible, then you should be able to use a provider’s SIP trunking service.
A benefit of VoIP calls with SIP Trunking is that since the user has their own PBX system, they’ll will be able to control exactly what happens with their own VoIP calls. Whilst there won’t be many benefits to the call quality, they’ll be routing benefits which will ultimately allow your business to operate more efficiently.
One of the many benefits of SIP trunks is that businesses typically save over 40% in costs when they adopt SIP trunks into their phone system. Saving is mainly due to the fact that SIP trunks can work with pre-existing IP-PBX systems, meaning that you may only need to purchase the odd equipment here and there.
The ability to be flexible is of utmost importance in a business and with SIP trunks, you’ll get just that. If your business has increased the number of its employees or is experiencing a surge in calls, then you can instantly add channels to your system with the click of a button.
Unlike traditional phone systems, SIP trunks can be delivered and deployed quickly. SIP trunks can be created and deployed on the same day, a stark contrast to traditional phone systems which can very well take a week to months to function properly.
Pricing varies. For example, here at Packnet, we charge less for a SIP trunk channel than extension because of two things. One, a customer is using their own PBX, therefore not taking advantage of extension level features. Second, the customer will be doing most of the work, which ultimately means that they’ll be using less resources.
Here’s a list of common ones:
Perfect for any large business with employees who need their own lines. SIP trunking is also preferable if as a company, you prefer to have all your phone system in one place for security and management reasons as well as having the added benefit of no extension costs.
