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.
kindly do let me know which centos version do you have.
That being said I would like to have a little chat about your project to better understand the needs of the project
regards,
