Methods and systems are provided for routing callers to agents in a call-center routing environment. An exemplary method includes identifying caller data for at least one of a set of callers on hold and causing a caller of the set of callers to be routed to an agent based on a comparison of the caller data and the agent data. The caller data and agent data may be compared via a pattern matching algorithm and/or computer model for predicting a caller-agent pair having the highest probability of a desired outcome. As such, callers may be pooled and routed to agents based on comparisons of available caller and agent data, rather than a conventional queue order fashion. If a caller is held beyond a hold threshold the caller may be routed to the next available agent. The hold threshold may include a predetermined time, “cost” function, number of times the caller may be skipped by other callers, and so on.
