Complete VoIP/GSM in/out calls solution

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. 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 Cisco 79xx series and newer phones with Asterisk servers 5) Asterisk with WebRTC 6) Asterisk Secure calling (SRTP/TLS) 7) Asterisk to gsm gateways 8) 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,
