VoIP & Asterisk IT Services

A complete service from Installation to Support and Maintenance


VoIP (Voice over Internet Protocol) phone systems replace traditional hard-wired office systems by using an IP-based network instead. It’s a flexible, cost-effective system for internal, national, and international telephone communications. VoIP phone systems can connect all branch offices and home workers to the company phone system, and calls between them are free. The phones on your VoIP network can be anywhere you want them to be: as dedicated phone handsets in the office; as an app running on an office or home PC; or even as an app on a mobile device. So, for example, staff travelling on business can use a software phone on their laptop or tablet, allowing them to stay in touch with both customers and the office easily, without phone charges mounting up. For any business needing secure links between international sites, the benefits of a VOIP PBX system can be dramatic, making communication easier for you and your staff, and saving significant costs on international calls.

What is a PBX phone system?

PBX stands for Private Branch Exchange. PBX systems can operate using either VoIP or via analog or digital phone lines. With a PBX phone system, the physical phone line coming into your business can be split into multiple lines. This allows you to support more telephones. PBX systems provide telephony features such as call forwarding, call transfer, call queue, auto-attendant and voicemail.
