I have to give credit to Luca Filigheddu and his team at Abbeynet for continuing to do their part to bring the power of VoIP to more people.

Originally when Abbeynet's Mozilla VoIP Extensions came out, I panned it. And while I will admit I'm still not a huge fan, I do like the direction is heading. Instead of being an Abbeynet-only tool, they've opened it up to other SIP providers.

A number of pre-defined SIP services are included in the latest plugin. However, there is now nothing preventing you from putting in your own SIP configuration. Good stuff!
