METHODS AND SYSTEMS FOR IMPROVING TRUNK UTILIZATION FOR CALLS TO PORTED NUMBERS

摘要

Methods and systems for improving trunk utilization for calls to ported numbers are disclosed. A method for improving media trunk utilization for calls directed to ported numbers includes receiving a call setup message associated with the call in a communications network (200) and determining whether the call setup message is directed to a ported number. In response to determining that the call is directed to a ported number, called party information is extracted from the call setup message. A lookup is performed in a number portability database (236) using the called party information to locate a routing number for the called party. A media trunk is selected for the call based on the routing number. The call is then routed through a media gateway (208) associated with the media trunk.
