  • Continued Move Towards Unified Communications

Best FUD I've heard this week: VoIP is insecure because you can simply put a bridge on an ethernet line and capture a stream. Hey, has anyone ever heard of alligator clips? ›››

This will allow users to have access to Live Communications Server-based IM and presence management over cellular networks, and will also function as a VoIP soft-phone over WiFi networks. Skype made two announcements... ›››
