Hi,
I have been working with Cisco VoIP since 2001 and Asterisk and freepbx ,trixbox/ce, 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 in addition to what you require I can also do Integration of Asterisk systems with Cisco CME , CUCM, Microsoft Lync, integration of cisco phones with asterisk,
can also setup asterisk/freepbx to use secure communication SRTP/TLS
kindly let me know if we can have a little chat about your project to better understand the needs of the project
regards,
