I’m a SIP instructor. I teach SIP Trunking courses on-site (I come to your location), and also offer on-line courses.

If you find this posting helpful, or are impressed by what you see, and would like to hire a SIP instructor, contact me or Alta3 Research.
FYI – I wrote this document off the top of my head. I may have omitted a step or two, or gotten a command wrong. […]
