Wheels I already dropped you an email, a VoIP solution would be my recommendation and that can be achieved in a number of ways. You say that the Merlin never worked right, Coral Tech is right that each system has it's pros and cons, how much traffic is pushed between the two sites? You could either go with a complete VoIP solution or use legacy Digital PBX switches with gateways, what I am saying is that you need a thorough site survey from a vendor that does care about your needs and will provide you with an honest cost effective solution (which may or may not fit within your 40K budget) rather than a salesman trying to meet this months quota.
