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 2027, 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 2027 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 2027 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.
SIP Trunking Managed Services
Cinos offers two flavours of SIP Trunking Managed Services:
SIP Trunking Components
As with many SIP Managed Trunking Services in the marketplace,
Cinos’ SIP Trunking Managed Service has two primary components:
Managed
Session Border Controllers (SBCs) are provided and fully managed as part of the service. Cinos will work with the customer to integrate the service with the customer’s PBX or unified communications environment.
Unmanaged
The customer provides their own Session Border Controller (SBC) and connects our service to their existing PBX or unified communications environment.
SIP Channels
A SIP channel provides the ability to carry a single concurrent inbound call from an external caller or make an outbound call to an external caller.
Numbers
We can provide new geographic (01 and 02) and non-geographic (03, 05 and 08) numbers, or port existing number allocations to our service.

How we differ
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.

Voice and telephony services play a crucial part in the day-to-day operations at EPUT. With 5,000 members of staff working across 200 sites, the Trust wanted to consolidate and modernise its existing legacy telephony estate.
