To tell you straight up, I use three softwares right now, extensions, IQL and mercedes, they all have good and bad things about them. I suggest you try them out BEFORE committing to any of them. Call them up ask for a demo and then MAYBE you yourself can make a decision based upon your specific needs. Again, for our shop we cater to different agents and thier specific needs. Therefore different software providers. Oh yeah almost forgot we also run INET as well.
