With BT announcing the switch off date for ISDN networks (2025), we explore the benefits of SIP Trunking (Session Initiation Protocol) as a cost saving, resilient and flexible alternative. 2025 may seem a long time away, but the migration period has already begun and small businesses must join the ride as soon as possible to ensure they don’t get left behind.

Since the late 1980s; the year ISDN was first introduced to the Nation, there have been huge connectivity developments. From super-fast Fibre Broadband that brings the UK extremely fast upload and download speeds, to Ethernet products that offer a reliable and fast solution for short distance networks. It’s even been reported that since 2014, BT has not installed any ISDN lines! With the new fibre infrastructure so widely available – and as such a cost effective solution for SME businesses, SIP is proving a popular alternative.

So what is SIP Trunking and how would it benefit your business?

SIP Trunking is a type of voice over IP technology, delivered over an internet connection. SIP Trunking is not only a highly-flexible alternative to ISDN 30 and ISDN2, but it also achieves a significant reduction in telephony overheads, saving businesses on line rental and call costs. All you need for SIP Trunking is an internet connection and a phone system!

Benefits your business can enjoy from switching to SIP Trunking are far reaching:

  • High Savings Potential
    SIP delivers less costly, more reliable connectivity than ISDN, with savings of up to 75% on line rentals and call costs. For larger organisations with multiple locations, there is also an opportunity to achieve free internal calls.
  • Fast Access & Prioritisation
    SIP is not restricted to any single site, so there is no risk of having to set up new lines in the event of an office move or being forced to change numbers. All you need is an internet connection and you can move anywhere and keep your same numbers.
  • No Limits & Highly Scalable
    SIP operates in a similar way to an ISDN30 line, but without the limit to the number of simultaneous calls per line. What is more, you can quickly raise or reduce the number of simultaneous calls you can make in line with business requirements.
  • Resilient & Secure
    Using our robust data servers, we provide a fully-managed trunk with as many channels as you require with built-in business continuity in case your IP telephone system goes offline. Handle any onsite disruption with ease by rerouting calls to an alternative location quickly and effortlessly.
