Abstract
According to various embodiments of the present invention, systems and methods for routing telephone calls from host switch to remote switch in a Voice Over Internet Protocol ('VoIP') network. A host switch in the VoIP network may be communicably coupled with a plurality of remote switches and with a public switched telephone network ('PSTN'); the host switch may receive a call from PSTN having signaling that includes a called party number field and/or a location routing number field. Based on the called party number field and/or the location routing number field, host switch identifies a target remote switch from among the plurality of remote switches that is associated with the called party number field by, for example, querying a database of associations between location routing numbers and/or telephone numbers and remote switches. Host switch then sends the call to identified target remote switch.
