ABSTRACT:
A method for policy-based routing of calls between nodes in a network, comprising: entering policy constraint indices for selected addresses in respective entries of an address translation table, the address translation table for accessing by a first node of the network to selectively translate attributes of calls based on respective addresses prior to transmission over the network to a second node, the policy constraint indices pointing to respective policy constraints for routing calls between the first and second nodes; receiving a call at the first node, the call including an address; accessing the address translation table using the address to determine whether the call requires assignment of a policy constraint by presence of an entry for the address in the address translation table and by presence of a policy constraint index in the entry; and, if the call requires assignment of a policy constraint, identifying a policy constraint with the policy constraint index, assigning the policy constraint to the call, and routing the call between the first and second nodes in accordance with the policy constraint.
