Not only is our Hosted PBX inexpensive to purchase, but it also is extremely cost-effective to own due to its extensive use of the latest VoIP technologies.

VoIP Telephony is not solely concerned with free calls between offices, but also offers wireless communications capabilities and remote user configurations.

Enables a group of geographically dispersed staff to function as part of your office PBX.

This gives a remote user the same functionality and features as office-based staff.

This allows calls to be transferred directly to the remote user’s extension or to act as part of a ring group.

Remote workers have the ability to connect to the office with ease and without the traditional costs involved. This means all calls from and to the office will be accessible through a three or four digit extension number and will be free.


We can put businesses in control of mobile calls from the office, sales agents and home workers, which enable mobile phones to become part of a self-contained corporate mobile network.

Essex Telephone Systems VoIP Mobile Solutions give businesses the ability to make, receive and transfer calls from their mobile phone as if they are an extension of the Hosted PBX giving users access to all calling features.

This quick and easy mobile solution will give your business complete control of your mobile communications.

Our SIP lines give our customers a fantastic alternative to traditional voice lines.
