Hi,
I have been working with Cisco VoIP since 2001 and Asterisk and freepbx ,trixbox, elastix since 2007. In addition to installing and just setting up asterisk/freepbx I can also integrate asterisk systems with different other SIP based systems e.g.
1) Asterisk with Cisco CME
2) Asterisk with Cisco CUCM
3) Asterisk with Microsoft Lync
4) Integrate Asterisk / Freepbx with different CRM (ZOHO , vTiger).
5) Integrate Cisco 79xx series and newer phones with Asterisk servers
6) Integrate Polycom, linksys, yealink, hanglong , fanvil and quite a few ATA/gateways.
7) Asterisk with WebRTC
8) Asterisk Secure calling (SRTP/TLS)
9) Custom dial plans.
kindly let me know if we can have a little chat about your project to better understand the needs of the project.
regards,
