Intelligent telephone call routing
First Claim
1. A method comprising:
- maintaining, by a telephone system of a company, a telephone call routing rule set including a call-back routing rule, wherein the call-back routing rule is configurable by an administrator of the telephone system and specifies one or more conditions under which incoming telephone calls received via a Public Switched Telephone Network (PSTN) will be recognized as a call back for which direct routing is to be performed and wherein the one or more conditions includes a timing constraint;
maintaining, by a call monitor of the telephone system, a session log in which a plurality of call session records relating to telephone calls between internal extension numbers and external telephone numbers are stored, wherein each of the internal extension numbers are associated with a telephone extension within the telephone system and each of the external telephone numbers are accessible via the PSTN;
receiving, by the call monitor, an incoming telephone call via the PSTN from an external telephone number;
locating, by the call monitor, a matching call session record among the plurality of call session records, by searching the session log for a call session record containing the external telephone number; and
when the incoming telephone call satisfies the one or more conditions of the call-back routing rule including a difference between a current time and a time stored in the matching call session record being within the timing constraint, then causing, by the call monitor, a switch of the telephone system to route the incoming telephone call to an internal extension number stored in the matching call session record.

Abstract
Systems and methods for intelligently routing an incoming telephone call to an internal extension based on the calling history are provided. According to one embodiment, a session log, containing information regarding sessions between internal extension numbers and external telephone numbers, is maintained by a call monitor of a telephone system. The internal extension numbers are associated with telephone extensions within the telephone system and the external telephone numbers are associated with telephones outside of the telephone system. An incoming telephone call is received by the call monitor from a telephone outside the telephone system that is associated with an external telephone number. It is determined by the call monitor whether the incoming call represents a call-back to an internal extension number based on the session log. When the incoming call is determined to represent a call-back, then causing a switch to route the incoming call to the internal extension number.
