Press about us
"Once the version 2 release is available to all users I would recommend it for people that want to open up
an Asterisk-based telephone system with Skype. Our set up will connect incoming Skype calls to an operator,
from where they are connected to the intended individual - thereby eliminating the need to have Skype on every
desktop and the need for people to keep track of their phones and their Skype applications."
