Hi,
I have been working with Cisco VoIP since 2001 and Asterisk and freepbx ,trixbox, elastix since 2007.
I have developed quite a few systems with crm and other Asterisk based wallboards and dash boards,
what we can add to it is WebRTC, so the agents can even take calls via a simple web browser,
That being said I would like to have a little chat about your project to better understand the needs of the project
regards,
