Welcome to my new site - VoIP Security

The main idea is to carry on from my old site (Telecom Pages) and offer help and advice, where possible, to anyone involved in the telecom trade, particularly the ones involved with Mitel equipment.

However, in view of the recent increase in people hacking into Business Telephone Systems and Voicemail / IVR systems I have decided to bias this site toward security issues and vulnerability analysis, hence the name change to VoIP Security.

At the moment all the work on this site is my own but if anyone feels that they would like to contribute just drop me a line.
