What makes VoIP telephone line services a better choice for business than traditional ISDN lines?

Firstly, let’s consider the basic difference between a digital telephone line (ISDN) and a VoIP telephone line (SIP). Each ISDN phone line is physically installed on copper cabling between the local exchange and a card in your telephone system. SIP telephone lines are delivered over a managed voice and data broadband connection, allowing you to remotely connect higher performance, lower cost and resilient phone lines with ease.

Following BT’s announcement that they plan to cease all ISDN circuits by 2025, and with more than two million ISDN lines the UK already being replaced in the last 10 years, maybe now is the optimum time to consider the value in transferring your organisation over to SIP.

To help you with your deliberations, we’ve collated some of the most compelling business benefits that SIP service has to offer.



1. A cost-effective way to communicate

It’s no secret that we all want to get the best price for our services, keeping our operation costs to a minimum without having to compromise on quality – and this is where our SIP services excel.

On average, we will reduce your line rental cost by more than 50% compared to ISDN lines and as well as this, you’ll benefit from reduced call costs, especially as free calls to UK 01, 02, 03 and 07 mobile numbers can be included as part of an upgrade package with Avandda.


2. Suitable and flexible for all

Having a communication system that’s adaptable to meet your needs is key to helping your business thrive. No matter the size of your company, whether a government organisation, a well-established large enterprise that deals with high call volumes, or a start-up beginning your business journey. SIP lines are completely scalable, allowing you to easily add and remove lines quickly and easily, so as your team evolves, your phone lines can too. If you’re moving offices, you can also keep all of your existing geographic phone numbers regardless of where you’re moving to, without facing any of the hassle or costs associated with digital lines.

4. Avandda SIP Call Manager

Avandda SIP Call Manager offers a powerful and effective business continuity solution, providing you with the ability to manage the journey of your incoming callers from the heart of the UK SIP network. Using your own dedicated portal via desktop and mobile access, Call Manager ensures that all of your callers are routed, queued and managed to ensure they are always answered, and never get engaged, regardless of the number of lines or staff you have available to answer them!

Our SIP Call Manager service is designed to ensure you keep your business communication functioning at its best, no matter what the situation. As standard, we equip you with a suite of control tools and features that will not only allow you to manage all of your business telephone numbers from one place, but will also enhance the performance capabilities of your existing business telephone systems:

Business Continuity and Disaster Recovery

Unquestionably, keeping your organisation operationally available to receive incoming calls is one of the most important factors when considering the capabilities of a business telephone system. Building effective BC and DR within an ISDN environment has always been prohibitively expensive and out of the reach of most UK businesses, leaving your organisation and your customer exposed to the limitations of ISDN.

This is where SIP lines and SIP Call Manager deliver, hands down, from a simple system or line fault situation causing disruption to business continuity to a full on disaster recovery scenario where your business premises become unmanned, SIP Call Manager has it covered. Through the creation of pre-built, multi-scenario call control plans to redirect your calls to alternate destinations based on number dialled, and prevailing situation.

These plans can be set to kick in automatically or by instant manual activation via your portal without your callers ever realising there is a problem.

Through our intuitive mobile app, you can access your call plans for each business numbers so you can instantly control their direction and termination. You can view performance statistics, call volumes and trends and also, if an emergency arises where the pre-built call plans are not suitable, you can create a new temporary destination on the fly to any telephone number or temporary voicemail service, thus ensuring complete business continuity and flexible working to benefit customers and employees alike!
