As far as I have seen, SER itself cannot offer conferencing services, right? Therefore I have also noticed that you recommend Asterisk, SEMS or others. My doubt is, how does SER contacts with those servers? Does SER supports MGCP? I tought not, but if this is true, how do they communicate? If anyone knows where i can see more info on SER conferencing, please let me know.
