does anyone suggest me any freeware VoIP billing solution like asterisk2billing.org i need a customised nice GUI to integrate with asterisk or trixbox.
I don't know a ton about asterisk and Vonage doesn't allow sip connections at any rate, here is what google returned. http://www.google.com/search?q=open...s=org.mozilla:en-US:official&client=firefox-a hope that helps, Nigel
