Firefox VoIP Client
libocannici writes "Abbeynet Labs has released the first version of a Firefox VoIP extension which is a full featured SIP user agent plugin for Firefox." The Firefox extension is completely stand-alone, with all VoIP functionality built directly into it. From one-click calling to SMS sending, this promises to be quite handy. All Internet calls are currently free, just requiring an abbyphone account, while PSTN calls have a small charge.
RTFA - you click on a phone number in a web page and it calls it. Not that cutting and pasting 10 digits would be that difficult, but there it is.

I maintain a salesforce database and this thing is brilliant. Just click the #.
There's also an IAX client for Asterisk fans called MozIAX available here.
Wengo btw is my operator of choice here in Europe with top-notch voice quality and reliability with prices lower than Skype. Only problem is their inbound number is France only atm. Did I mention that they have a working Gaim port?
Artificial intelligence is no match for natural stupidity
You still don't need to build the VOIP into the browser. Just a Greasemonkey script to convert plain-text telephone numbers into <a href="tel:..."> links and a handler to pass off tel: links to an external program just like mailto: links are handled.
