ISDN, SIP Lines and Hosted Voice Services

For all businesses, personal contact with customers is a significant factor for success and therefore the quality of your telephone lines and calls is key. At Telephone Number Solutions we benchmark your services and technologies you are using against what is available so you can get a more cost effective service without compromising on quality.

Order new lines to include ISDN &SIP along with Hosted IP Voice Services. Simply transfer your existing lines (and calls) seamlessly to benefit from savings on connection charges and monthly rentals and possibly better customer support – we can give you insight on how to achieve this along with access to free or inclusive call packages

We can manage the whole process and a migration of your line rentals and calls takes just ten days – we provide professional advice on the suppliers available


Call charges are decreasing (or free) and when you use SIP (VoIP) technologies you might even get calls free (included) as part of the service from your chosen supplier. We can assist you in achieving call savings and obtain inexpensive and bespoke call rates for your business.

Customer case study

A national business association with a head office in London and eight regional offices throughout the UK get free calls between all of their locations and this includes home workers.

All locations (offices) have standard telephone systems in place and the service we provide does not involve any SIP or VoIP lines (or calls) – we simply give them free inter site calls.

In return the company agreed to a 24 x month contract for calls and lines at very competitive rates and this has delivered significant savings.
