When Tough Mudder set up the London office, Voicelinx deployed a fully functioning phone system including voicemail to e-mail and conferencing within a day of Internet becoming available. We have 31 extensions in our London office. One of the major benefits of using Voicelinx is their personal attention and in depth knowledge this led to us installing a Polycom IP7000 conference phone which allows us to join skype calls into our regular conference calls.
