How much does the service cost and what are the components that make up the service?

SDSL Circuit

First you need an SDSL circuit. Dependent upon the distance you are from the telephone exchange, an SDSL circuit can support up to 14 concurrent calls with no compression. If you require more concurrent calls than this then you need multiple SDSL circuits.

The monthly charge for an 1:1 SDSL circuit is £44 per month and minimum contract length is 3 month.

SIP Trunks

Every concurrent call that you require will need a SIP Trunk. We charge a one off setup fee and an ongoing monthly rental charge for this service.

• Set up per trunk - £10
• Monthly rental (per trunk) - £4

Analogue Line

You will require an analogue phone line for the SDSL circuit. This can either be an existing circuit or we can supply one for £12 per month

DDI Numbers

We can supply DDI numbers in blocks of 10 for any geographic region. We can also port your existing numbers into our service.

• Planning Fee for DDI numbers - £25
• Set up fee per block (10 DDi's) - £5
• Monthly rental per DDI range (10 DDI's) - £1

* Maximum SDSL speed is 2MB but this may be less depending on your distance from the exchange. Once we have your postcode we can confirm the anticipated line speed.
