SIP Trunking

SIP Trunks provide a modern, cost-effective and robust connectivity solution.

If you’re not ready to make the move to a fully hosted telephony solution, then SIP Trunking might a perfect, low-cost alternative for you. SIP Trunking provides a next generation connection between your existing switchboard (PABX) and our core platform, using a data circuit to replace your existing phone lines.

There is no need for new numbers or handsets and your existing switchboard features can all be retained, or even improved by bolting on some core features, such as call recording

SIP technology provides a modern, robust connectivity solution, so there is no need to compromise on quality when you make the change from ISDN to SIP. Our next generation quality is reliable, resilient and can be cheaper to buy and use.

What is a SIP Trunk?

In simple terms, a SIP Trunk is a next-generation phone line that works over a broadband connection.
It is designed to replace the outgoing ISDN lines.

What type of business are SIP Trunks aimed at?

If your business makes phone calls from a landline, SIP Trunks could be for you.

How do SIP Trunks work?

SIP Trunks can be implemented in two ways:

Using SIP Lines onto a new or existing telephone system*. It is seamless and works behind the scenes.

Using a Hosted System, which means no telephone system is needed. SIP Handsets are supplied and work over Cat5 cables within your office, via a data switch and your broadband router.

How much do SIP Trunks cost?

Cost is generally relative to the requirements of the business or the individual.
We quote based on the needs of your business.

What else do I need to start benefitting from SIP Trunks?

For the Hosted solution, you will need a dedicated fibre broadband connection, a PSTN/Copper Telephone Line

For SIP Lines, you will need  a dedicated fibre broadband connection, a PSTN/Copper Telephone Line, and a compatible telephone system.

No Downtime with Auto Failover

Could your business cope without a phone connection for several days?
Our SIP Trunks can be configured to automatically route calls to an alternative number in the event of a service disruption.

SIP technology provides a modern, robust connectivity solution.

We found the advice and support form Octagon in selecting a new phone system helpful when we were sourcing our new system.

The Ridge Medical Centre moved into a brand new purpose built premise and required a new telephone system to handle the large amount of calls they receive each day to provide a service that their patients would be happy with.
