SIP is now rapidly replacing traditional ISDN and PSTN services

With legacy ISDN and PSTN circuits no longer orderable as of 2020, and the Public Switched Telephone Network (PSTN) being switched off entirely in the United Kingdom in 2025, SIP Trunking solutions offer the modern telephony means to connect your calls between your phone system or cloud service, and external users.

PSTN to SIP and ISDN to SIP

With these deadlines looming, businesses whose telephony contract is up for renewal need to start exploring alternatives now. Even if you have a few years left on your contract with PSTN and ISDN lines being switched off in 2025 you must start thinking about how you’ll make the move to SIP/VoIP solutions.

And this is where Cinos comes in. Whether you are looking to move from PSTN to SIP, ISDN to SIP or to a hosted IP phone system our experts are here to help. We have more information below on our SIP services but please do not hesitate to get in touch. Sometimes it is easier speaking with an expert and we would be happy to discuss the options you have.

Pay as you use and bundled minute options

Our SIP Trunking services provide both pay as you use and bundled (inclusive) minute options, allowing for complete flexibility and cost predictability in how you consume the service. We also offer a free cost analysis service where we will assess your current call and line rental spend and provide predictive cost savings on moving to our service.

We offer connectivity from a single, up to unlimited SIP channels for concurrent calls, and the flexibility to scale the number of channels based upon demand.

Our bundled minute offer includes unlimited SIP calling minutes to UK National (numbers starting 01/02/03) and UK Mobile (UK mobiles starting 07)*.

Do you rely on ISDN services?
Now is the time to act.

For many years the Integrated Services Digital Network (ISDN) has been the standard and trusted connectivity to the PSTN for PBX environments. Even with the introduction of IP based phone systems, ISDN was still the go-to choice to provide either the main PSTN connectivity, or a backup to the newer options of Session Initiation Protocol (SIP). However, Openreach will be switching off the UK’s PSTN by 2025 and migrating all customers to internet enabled telecommunications.

In the Cinos Blog, Jono Darlington, Solutions Architect at Cinos explains why organisations across the UK must act now if they are still relying on ISDN services. With Openreach announcing they will stop selling PSTN and ISDN services to new customers in September, Darlington highlights how Cinos can assist organisations with our SIP Trunking Service to ensure continuity of service and take advantage of integrated communications, including messaging, presence, and video.

How we differ

Offering you a flexible approach to suit your needs.

Cinos offers complete flexibility in how we deliver your calls. We can deliver your number ranges (DDIs) to multiple sites to provide for business continuity and high availability; or split your calls between legacy phone system and cloud service, such as Microsoft Teams or Webex for example.

We also license SIP channels centrally, meaning that you pay for the total number of concurrent calls you require over all platforms, rather than worrying about how many primary / active or backup channels you require.
