SIP Trunking

If you currently use BT ISDN Lines, now is the time to switch.
SIP saves you money and less complicated than you may think.

SIP trunks are phone lines that operate via broadband/data connections. SIP (Session Initiation Protocol) replaces traditional BT Lines (ISDN), connecting your business telephone system to the PSTN (Public Telephone Network).

BT are planning the big ISDN switch off in 2025 and no new orders will be accepted from 2020.

All you need to implement SIP is a fast, robust internet connection.

SIP provides low-cost calls!

The majority of SIP calls to UK landlines are free, and a much lower cost of calls to mobiles than from ISDN lines. International calling is also less expensive. We can check your bills and provide an average cost saving based on current usage.

SIP Saves line rental too.

ISDN line rental is generally more expensive, and less flexible. Adding or removing SIP lines (the capability to make concurrent calls) can be turned up or down depending on your current requirements. Businesses experiencing rapid growth can increase capacity without waiting for an engineer visit. Additional users can be added at any time simply for the price of a new handset.

Phone Numbers on SIP

SIP is the most flexible solution for phone numbers. If you require a one-time campaign number, an 0800 or local number for another city or even Multiple phone numbers to ring a single phone? It can all be done through SIP.

New to SIP? You can keep your existing phone numbers by porting your numbers to your SIP provider. Moving office? Your phone numbers transfer with you to your new internet connection. This is achieved because SIP uses cloud technology thus has no physical location – your SIP trunks can be delivered to any broadband connection in the UK

SIP for Multi-site connections and Home Workers

SIP is delivered to your local device called a PBX (private branch exchange). Calls are then routed to your phones around the office. But they can also be delivered to remote connections for home workers and to another PBX in a separate office.

SIP Delivers UC&C (Unified Communications & Collaboration)

The SIP protocol is designed for more than just phone calls. Video calling, instant messaging, file sharing, and screen sharing to multiple end-points including handsets, mobile devices, and computers. A single software solution is provided for all devices and operating systems making collaboration simple.

SIP is secure?

When installed correctly and maintained with software and firmware updates, security should not be an issue. Our SIP trunks will monitor your connectivity and protected by dedicated firewalls. Call monitoring will be set up and should the system become comprised, all calls can be automatically blocked.

Converting from ISDN to SIP

Most recent PBX systems are compatible with SIP, but if not it’s relatively simple to swap old for new.  You don’t need to replace your handsets either. Hybrid PBX systems can replace your existing PBX and work with your existing handsets. Although in the long run, it may be worth looking at a completely new system.

SIP is dependent on bandwidth

SIP trunks depend on a strong, reliable internet connection. It’s advisable to speak to us about your connection, and we can run the necessary tests. We may recommend upgrading your broadband to meet increased requirements

SIP Disaster recovery plan

Should the worse happen: Power outage or loss of broadband connection, your phones will stop working. As SIP trunks are managed in the cloud steps can be put into place to make sure you remain connected. Calls can be quickly diverted to alternative landlines or mobiles without the need for an engineer visit. Having a disaster recovery plan pre-arrange makes the switch fast and stress-free.
