Never miss a call and stay connected with your customers, suppliers and people with our tailored business telephone line services.


From business land-line services to SIP Trunking, our reliable and cost-effective business telephone lines with helpful call features are perfect for any size of company. If you want an ISDN line or a standard business land-line solution, our cost- effective broadband lines and calls packages provide the perfect answer.


Broadband & Phone

Combine your business telephone and broadband with our cost-effective deals. Making calls to customers, suppliers or colleagues is an essential part of business and connecting to them is important. And because it’s vital, we believe it shouldn’t cost the earth - our business broadband and telephone deals are flexible and cost-effective to suit any requirements and budget.

Integrated Service Digital Network (ISDN) Lines

ISDN is perfect for multi-line business telephone networks. With options including ISDN2 and ISDN30, these digital lines use the national copper telephone line infrastructure.


ISDN is soon to become end of life and is being replaced with new modern technology (take a look at our IP Telephony solutions web page). From September 2023, Openreach will phase out the supply of new connections and there will be no new line installation for Single PSTN Lines or ISDN. At the end of December 2025, these fixed lines and services will be switched off, the network deactivated and services withdrawn.


We know that every business is different and that you may not be ready to support VoIP but we can still help. Our ISDN lines and calls service gives you voice calls and can also be combined with internet access, giving you both connections in one package.

Session Initiation Protocol (SIP) Trunking

Our SIP Trunking product can help you make the journey into the cloud and our dedicated team are here to provide full telecoms support. Session Initiation Protocol (SIP) Trunking is a way of providing telephone lines using data rather than fixed lines. It gives you the ability to make and receive calls using IP technology and is a natural replacement for fixed lines for your legacy PBX or on-premise phone system. In addition, it offers greater flexibility and resilience at a lower price.
