One big problem for companies in handling customer calls is uninformed answers. That is, the person answering the call has no idea who is calling or why. Large companies solve the problem by using call centers, which integrate high-end CRM (customer relationship management) systems with sophisticated call-handling systems. For smaller companies, integration of hosted or premises-based IP PBXes with hosted CRM services is a good solution, eliminating the need for premises-based CRM systems. And a new "rich calling" service launched by Ringio at this week's eComm conference simplifies things even further. For a flat rate per user, it provides both IP PBX and basic CRM functions in a single hosted service.
