I should setup a VOIP network. I installed Virtualbox and install ubuntu server on a virtual machine and installed freeswitch on it. I also installed Ekiga softphone on my ubuntu desktop. Now , I need a manual or tutorial to help me how to work with freeswtich, how connect my softphones to my PBX.
there's an excellent book which explains the FreeSWITCH in details. You need to read that before you go any further.
as an alternative, you can, of course, order consultancy and training from whomever is able to offer it
