Secure VOIP

using GSM phones, Asterisk and IPsec/openvpn

Workshop about how to configure all the parts to get the GreenPhone/XDA/Motorola phones working with VPN software and SIP to an Asterisk on VPN. This workshop goes deeply into software/tech bits that cannot be delved into during the presentation on 28.12.2006. The presentation focusses more on VOIP security issues in general and our overal design of the secure phone infrastructure.. This workshop takes place a day after that presentation. Bring your phones and/or laptops and connect to our secure PBX!
