We offer hosted solutions as an alternative to traditional ISDN phone lines for small to medium-sized businesses. For most businesses, switching to a hosted solution is no longer an option but a necessity. In 2025, BT will switch off their ISDN and PTSN networks and migrate to a single IP core network.
Hosted phone systems were previously unreliable. However, broadband technology and business fibre broadband have made it possible to get faster speeds and better performance.
Seriun 3CX offers flexible options and features designed specifically for your business needs. Our IP network offers a comprehensive solution for businesses that are in search of a platform that is scalable as your business grows.
Clear communication is a core business need. Providing high-quality communications is one of the key advantages of using SIP trunking. We ensure that you can send and receive phone calls as clearly and efficiently as possible.
Our SIP platform gives your business a competitive edge. With clearer communications comes improved productivity. Employees can reach each other on the first try, saving time and enabling unified communication. Employees can also work remotely which allows them to continue being productive even outside the office.
Integrated Services Digital Network allows simultaneous digital transmission of voice, data, and video among other network services. However, ISDN is getting phased out in 2025. Small businesses who cannot afford any breaks in transmission are encouraged to make the switch early.
SIP trunking has grown popular because of its significant cost savings to users. However, SIP also has a variety of advantages over ISDN. While ISDN offers digital solutions that analogue PSTN did not have, it still requires users to pay separately for voice and data.
SIP providers use an application layer protocol based on IP. This allows users to access both data and voice on the same channel. SIP is a modern solution that gives users access to both services through a single pipeline.
ISDN uses a traditional copper telephone network to give users access to voice and data. SIP trunking delivers these services via the internet.
While both ISDN and SIP allow data to be carried over, SIP is more efficient and cost effective. ISDN is also going to become obsolete as more businesses opt for IP telephony. SIP also allows businesses to purchase on a line by line basis which means you only ever pay for what you need.
The advantages of SIP trunking far outweigh those associated with ISDN. Seriun is a leading SIP provider offering a wide range of telephony systems and communication solutions that are designed to coordinate with your business and customer’s needs.
