Help! Honestly, I really need some help getting a Skype replacement up and running.
ekiga is not going to talk to skype connection. Both parties will need to be using the same protocol. Basic newbie linux problems are the firewall, audio device selection and same for codecs. Here is a script you can use to check your LAN firewall then your WAN router firewall. Hopefully Ekiga developers will create a LAN/WAN test one of these days.
