What are the benefits of having a SIP number for your business?

More and more organisations in the UK are turning to SIP phone systems as a solution to their communications needs.

With SIP trunking you could make substantial savings on your business phone bills and consolidate all of your communications channels into one system. 

With so many of us working from home it also enables you to connect with colleagues and clients instantly, regardless of their location.

So let’s take a look at some more of the benefits that SIP calling could bring to your business.

What is SIP calling?

SIP calling, or Session Initiation Protocol calling, is the process of transmitting voice call data over a SIP trunk, or channel. 

You may have heard it referred to as Voice Over Internet Protocol (VoIP) calling, or cloud-based calling.

Essentially, a SIP trunk provides you with a phone line via your broadband connection and allows you to collaborate with messaging, video chat and conference calling features.

It’s simple to scale the system up to fit your business requirements, plus SIP phone system users also get additional features such as call reporting and call recording to help enhance productivity.

How much could I save with a SIP phone system?

Pretty much every telecommunications firm will tell you how their products and services could save you money, but with SIP trunking your call costs really could fall dramatically. 

SIP phones offer cheaper rental costs than traditional landlines and generally there are very few hidden costs. With some SIP calling packages you’ll get free UK landline and mobile calls using SIP trunking, with major savings on international calls too.

Flexible and scalable

One of the many benefits of SIP calling is that it’s extremely easy to scale your system up or down depending on your business requirements. 

With SIP phones there is no lengthy installation process, adding extra lines just takes a few mouse clicks – and should you move premises you can take your numbers with you without geographic constraint.

SIP calling allows you to port any existing phone number over to the new system, so customers and colleagues won’t notice the difference when you make the switch.

It offers great benefits and flexibility for how your business appears to the outside world, as numbers can be created for any area code in the UK and many overseas countries, even if your company is not physically based there. 

If you want staff to appear to be calling from London despite them being located in Leeds, SIP phones give you that ability.

With colleagues working remotely, including from mobile devices, the office number will be presented when they call out, no matter where they are, as long as they have an internet connection.

The ability to quickly add extra trunks when they’re needed is what makes SIP numbers so attractive to many companies looking to increase their communications capacity.

Reliability and resilience

In the early days of SIP trunking had a poor reputation for reliability, which was often due to slow internet connections. 

But with the advent of high-speed internet broadband and fibre these issues have been addressed and the technology is considered stable and trustworthy.

SIP lines have priority on your bandwidth, ensuring phone calls will never lose quality.
