Which Phone Line should I choose?

Your business’s phone system cannot function without choosing a type of phone line. So, before you choose an all-singing-and-dancing phone system, you’ll need to consider what phone line will be the best fit for you to get the calls to and from your phone system.

A phone line needs to give your business:

Flexibility with your phone numbers– High quality calls – Business Continuity– Confidence that it won’t hinder your growth plans

There are two main contenders for phone lines:

ISDN Phone Lines are a traditional type of phone line which uses physical lines to transmit voice calls. You have to purchase an ISDN phone line for every 8 channels. You won’t be able to purchase any additional lines past 2020. This technology is being phased out and will be obsolete by 2025.

SIP Phone Lines
uses virtual lines (internet lines) to transmit a phone call. It is the most superior type of phone line. This is mostly down to the flexibility it gives you, the speed in which you can add/remove lines, the quality of the calls and the lower call costs.

If you choose a SIP Line, you may also want to choose a phone line management solution which increases your control over your phone numbers and how calls come into your business. We recommend an Inbound Phone Line Management solution.

There isn’t one size, fits all, so please do get in touch to discuss your requirements!
