Next year BT will be ceasing the supply of ISDN (Integrated Services Digital Network) and PSTN (Public Switched Telephone Networks), followed by a full migration by 2025. So, if you are looking to renew a 3-5year phone line contract, you might want to rethink your options as SIP, Cloud and Hosted technology will be taking over.
According to Ofcom (the UK’s communications regulator) there are 33.2 million fixed landlines in the UK (including ISDN). Approximately 7.6 million of these belong to businesses. BT is determined to slowly phase out legacy networks and platforms. The intention being that all customers will migrate to an IP (Internet protocol) network as soon as possible.
Hosted telephony is becoming more and more popular due to its low costs and high call.
The two main types of VoIP Telephony
1: Hosted VoIP (Voice over Internet Protocol)
Hosted VoIP is completely cloud based and best suited to SMEs who are looking for fixed cost business telephony with added functionality and reduced call costs. Each user has their own line and calls are routed through the internet.
2: SIP (Session Initiation Protocol) Trunks
Similar to traditional Telephony, you will have an on-premises telephone system but route your calls using SIP Trunks rather than ISDN channels. SIP Trunks are best suited for larger businesses as this type of Telephony can prove more cost effective than Hosted VoIP if there are a large number of users.
Will my business benefit from the switch over to SIP?
Yes! SIP is now a well-established technology and is the preferred solution for businesses of all sizes, in many ways outperforming ISDN. Organisations that still use ISDN can switch comfortably and quickly to a SIP service, as numbers can be ported and retained and the whole service can be set up within weeks. This is a key opportunity to also upgrade your hardware to ensure you have the necessary features to operate your business.
