A Session Initiation Protocol (SIP) trunk is a voice over internet technology which can deliver telephone and video services on a global scale, using computers and mobile devices with a secure internet connection. They are set to overtake ISDNs once the big switch off has happened in 2025.

It’s evident that businesses are future-proofing by implementing VoIP systems into their telecoms strategy and now is the time to make the transition to SIP because by 2020, businesses will be unable to buy additional ISDN channels or upgrade existing ones. Below are a few benefits of SIP Trunking.

1. Reduce Bills

Cost reduction is a major priority for most businesses. This is particularly true for SMEs – the average UK SME has seen their costs rise by 3.2% in the past year!1

SIP rentals are usually between £5-10 pm per channel and with easy flexible scaling, you’ll never end up paying for channels you never use. Furthermore, the cost of your calls will decrease as all internal calls stay within the company’s WAN.

2. Enhance remote working

The modern workplace is changing:

  • 60% of employees’ ‘time’ is spent away from their desks 2; yet…
  • … 33% of employees cite poor communications as their greatest challenge when remote 3; and
  • 84% said they could work productively if given the right tech 4

SIP trunks can connect employees to a single telephony system to any device or location and allow calls to be redirected to any phone, when connected with cloud-hosted PBXs.

3. You can keep your number

If you move office, or more offices have been opened in different locations, you can keep your advertised number with SIP trunks. Therefore, your infrastructure can evolve with your business needs with efficiency and minimum downtime.

4. Keep going in the event of a disaster

Having a disaster plan is key to keeping your business running and avoid any potential financial risks. Quick and easy call forwarding means that your business can remain operative if your phone lines go down.

5. Enabling Unified Communications in the cloud

If you’re thinking of transitioning your UC into the cloud, then you’ll be pleased to know that SIP trunking and UC go hand in hand. SIP trunking allows for voice, data and email directories to be combined, meaning collaboration and sharing is made much easier, something that wouldn’t be possible with an ISDN-based system.
