I am interested in building a home lab to learn Communication Manager and Voicemail. I am a hobbyist that would like to learn to configure the switch, and few digital phones, analog phones, voip phones, PRI, copper trunks, voicemail, auto attendant, coverage groups, ARS, and more I can't think of right now. I bought a G700 on ebay but it didn't come with an S8300. Does anyone have any tips on my options to build a home lab, with or without this G700?
