Hosted Systems:


Hosted systems are becoming increasingly popular. They allow our clients to start with a low cost phone system, which is easily scalable as staff join the business.

They provide the ability for clients to work remotely while still maintaining the internal phone system features. An additional benefit is that they use your existing internet connection, and allow you to benefit from SIP price tariffs.
