Help with VoiP if possible

Hi guys and support. Sorry for my question as it not relevant to the technologies on this site :slight_smile:

I was wondering if you know of any good sites which can provide training for VoiP. (possibly in a format similar to which Khawar teaches, so I am able to understand all bits and pieces for VoiP ( don’t like doing things mechanically).

Thanks very much and again sorry for my question … any help appreciated :slight_smile:
