VoIP Office Based Telephone Systems

Hosted or Cloud based telephone systems are not always the correct solution for a business.

For example if you have  a small number of lines compared to internal extensions it can be far more cost effective compared to the hosted rental cost,  to have an office based VOIP PBX system with SIP, ISDN or Analogue lines, that offers a full range of features such as voicemail, Voicemail to Email , Call logging, call recording and much more.
