Hi, I am new to GNUgk (& for that matter all things to voip). I am planning on setting up a commercial VOIP service. I am planning on selling minutes through IP phones and pc2phone s/w. One of my friends advised me to use asterisk. I dont understand the difference between a softswitch and a GK.Could someone plz clarify as to whether I must go for softswithc or GK. If anyone has any reading material on the difference between GK and softswtch it would b gr8. thankx in advance luqman
