My next issue comes from fact of my limited mobility, I am frequently not able run fast enough and mostly I miss the call. I need to have phone in the kitchen, living room and garage to be able to respond the calls. I am using another SIP provider currently who allow me to setup home PBX, but I would like to use TPG.
