Hi,
I have been working with Cisco VoIP since 2001 and Asterisk and freepbx ,trixbox, elastix since 2007.
I'm very new to the site so trying to bid as low as possible and get better reviews as much as possible.
That being said I love working on Asterisk implementations as I feel Asterisk gives you freedom to utilize full potential of VoIP, while WebRTC is actually future of the VoIP, so the project is really an amazing couple of technology.
to be able to finish the project i would also recommend to be able to use skype as well as email to communicate.
