Parking and routing network calls and sessions

摘要

A device may process a call, receive a request to forward the call at a call extension point, obtain information about parked calls from a queue that stores information associated with the parked calls, determine whether the call may be parked or forwarded to a terminating device based on the information, park the call at the call extension point when it is determined that the call may not be forwarded, and forward the call to the terminating device when it is determined that the call may be forwarded.

1. A method performed by one or more devices, the method comprising:
processing a call; receiving, at a call extension point, a request to extend the call to a terminating device corresponding to a multiple termination set; obtaining first parameter information indicating that each terminating device of the multiple termination set is handling other calls, and that a queue associated with the multiple termination set is accepting queue elements corresponding to parked calls at the call extension point; allocating a queue element representative of the call, and inserting the queue element into the queue, wherein the queue element is assigned a first queue index value based on the first parameter information; parking, responsive to the inserting, the call at the call extension point; extending the call to the terminating device responsive to second parameter information that indicates that the first queue index value is less than or equal to a second queue index value representative of a parked call to be unparked from the call extension point; and transferring, based on the extending, the queue element from the queue to the multiple termination set representative of the termination device, wherein the multiple termination set is allocated in a database in which the queue and queue element are allocated.
