Have been involved in telephony since the late 1970's and started installing 1A2 Key Systems in high school. Have installed and managed PBXs from Siemens, AT&T, Toshiba, Panasonic, Mitel and Nortel. Also am an MCSE.
Currently am VP of a relatively large legal services firm in California with additional offices throughout the US. Very comfortable with MS Windows, Servers, Exchange, (All versions) and have a special place in my heart for automated deployment of everything.
Am currently playing with PBXnSIP as a solution for branch offices and should be rolling out something in the near future.
My pet project is getting the AT&T lady to redo all the prompts for asterisk and every other VOIP system. Found her, recorded most of them and am currently in beta. Might even make a set for PBXnSIP! Let me know if you want a set.
