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 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 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
associated with the media trunk.
