ONSITE PBX / SIP
A flexible and cost-effective alternative to ISDN
Reduced Telephony Costs
Reduce your business's overall telephony costs with benefits like free site-to-site calls, cheaper line rental, call rates and all-inclusive minute packages.
Improved Call Handling
Voice recording, on-hold music, emergency call re-routing, and caller detail information are available, meaning you're always in full control of the way your calls are handled.
Flexible & Future Proof
SIP is an ideal replacement for ISDN without needing to replace your PBX. Easily scalable as your business grows, it's ideal if you move and want to keep existing numbers.
On-premise telephony solutions to suit your business
An on-premise phone system is a physical device based at your business site, known as a PBX. These can use both traditional (ISDN) or more advanced (IP) technology to make and receive calls.
SIP (Session Initiation Protocol) allows your on-site PBX to enable VoIP (Voice over Internet Protocol) calls (i.e. calls made over the internet) as a next-generation telephony solution and a more robust and efficient alternative to ISDN, which is gradually being phased out in the UK.
Compatible with all the leading PBX brands (including Mitel & Avaya), SIP is a fast-growing technology, becoming known in the market as the communications solution of choice, offering greater flexibility and better call quality due to the use of IP telephony.
Whether you want to keep your existing PBX and/or convert to SIP, install a new on-premise system, or if you simply don't know, we are here to help. We will always recommend the solution that is right for your business, budget and future plans.
