Upgrade your business telephony with SIP Trunk solutions that are scalable, flexible and reliable

Solution IP are Bristol and Southampton based SIP Trunking providers with experience in upgrading a company’s telephony infrastructure to a new, flexible, cost-friendly SIP Trunk model.

What is SIP Trunking?

SIP Trunks (Session Initiation Protocol) are connections that link the PBX  at your business premises to the Public Telephone Network (PSTN). These connections are delivered via an IP or Assured Broadband connection, meaning call quality is reliable, and there is no risk of downtime during an event or disaster, which could otherwise impact your business. SIP Trunks are a great alternative to ISDN, which is slowly being phased out and which will be switched off completely in 2025.

What are the business benefits?

1

Grow your business quickly

SIP’s number one advantage is that it is completely scalable. Depending on what your business requires, you can scale your telephony up or down with ease. You can instantaneously add extra SIP trunks, and increase your capacity to make and receive inbound and outbound calls at the same time. This is very important to those businesses who are expecting growth, and those that experience seasonally-related busy periods, when beefing up telephone resources to cope with increased orders, sales and enquiries is greatly beneficial. SIP Trunking allows you to run your business in the way that you would like, with no restrictions or barriers to growth.

Become a truly flexible business

SIP is an extremely versatile form of telephony. You can easily manipulate outbound numbers, so if you are moving office and wish to keep your existing telephone numbers this is ideal. SIP allows for the setting up of multiple geographic numbers, routed to the same location. You can set up Non-Geographic numbering easily, including a series of Non-Geographic numbers for those companies wishing to have a city based presence. Calls from a mobile phone under a specific number, regardless of the user’s location, are also possible.

Rationalise your telephony across multiple sites

If your business has multiple sites, then you can use SIP Trunking to help you rationalise the number of PBX’s you need to maintain, including any maintenance costs associated. By reducing the number of ISDN connections into individual PBX’s at each site, you can help centralise and distribute calls more effectively and help with any disaster recovering planning at the same time.

Be more resilient

SIP is so flexible and so instant that you can confidently be prepared for any situation. You can put in place a disaster recovery plan, set up backup facilities, and ensure business continuity with the help of SIP Trunking. Calls can be rerouted instantly in the event of an emergency, and multiples DDI’s pointed anywhere you wish without having to refer to a middle man first. Some companies choose to use SIP Trunks alongside their existing ISDN infrastructure to make sure that one or the other acts as a fail-over. However you choose to deploy SIP, it serves to make a business much more resilient, giving you peace of mind that business continuity will always be possible.

How does it work?

Your company’s voice traffic is carried over an Assured Broadband or a Managed Internet connection using SIP Trunks. This connection is specifically designed to carry voice traffic, which means high quality of calls. The connection is essentially an end-to-end service, and comes with availability guarantees, voice channel guarantees and voice Quality of Service.

For SIP Trunking to be enabled, your existing PBX hardware needs to be compatible. The SIP Trunks that Solution IP provide are compatible with most of today’s leading PBX brands, throughout the UK.
