SIP Trunk

SIP trunking is the new technology of choice for UK businesses that have outgrown their outdated ISDN service.

BT recently announced they are switching off ISDN by 2025 and may even stop taking any orders for ISDN (including additional lines for existing ISDN customers) as early as next year… so there has never been a better time to make the move to an efficient, future proof and cost effective solution for your business’s lines and calls.

A SIP Trunk is a cost-effective means of connecting a phone system (PBX) to the outside world to make and receive telephone calls using an internet connection, whilst providing features and benefits that complement the existing features of the phone system.

SIP Trunks are

  • Cost Effective
  • Flexible
  • Scalable
  • Portable
  • Reliable

When coupled with a SIP Trunk, Premise based telephone systems provide the peace of mind of a tangible asset that is future proofed for years to come whilst still enjoying the advantages of ever evolving technology.

What is a SIP Trunk?
A SIP Trunk is a cost-effective means of connecting a phone system (PBX) to the outside world to make and receive telephone calls using an internet connection, whilst providing features and benefits that complement the existing features of the phone system.
What do I need?
Just a compatible phone system. We can provide everything needed as a complete package for ease of management and support, including dedicated or shared Broadband and the underlying analogue line. Alternatively, you can use an existing internet connection.
Can I keep my existing phone numbers?
Yes. We can port existing incoming telephone numbers from nearly all UK networks.
Can I get new phone numbers?
We can provide UK geographic telephone numbers in 99% of STD codes. These are requested via our portal and are live within 24hrs.
How long does it take to set-up?
SIP Trunks are live within 24 hours of placing an order, not weeks like ISDN or analogue.
What if I move premises?
No problem. A great advantage of SIP Trunks is that we can provide service at any location with a suitable internet connection. This does not have to be within the same exchange area or STD code of your current phone numbers. This makes premises moves easy and stress free… we simply pick up the PBX, move it, and plug it in at the new location and calls will continue seamlessly.
