A system for selecting communication routes based on multiple criteria is disclosed. The system can dynamically update route ranking criteria without loading new data tables. Further, the system can be implemented in the context of a route ranking system that provides a list of routes for processing or completing a call. The list of routes can be generated in a ranked order to facilitate attempts to route the call based on the predefined routing criteria. Further, the route ranking system can determine the list of routes based on one or more criteria including, for example, margins, call type, and vendor ratings, to name a few. Advantageously, modifications can be made to values associated with the routing criteria without requiring the loading of new tables associated with the routing criteria. These modifications can be associated with an expiration condition thereby enabling increased flexibility in determining the list of routes.

Novel tools and techniques are provided for implementing originating number or address -based route determination and routing. In various embodiments, a computing system may receive, from a first router among a plurality of routers in a first network operated by a first service provider, first SIP data, the first SIP data indicating a request to initiate a SIP-based media communication session between a calling party at an originating address in an originating network and a called party at a terminating address in a terminating network. The computing system may determine a communication route among a plurality of routes through the plurality of routers in the first network for establishing the SIP-based media communication session, based at least in part on the originating address, and may establish the SIP-based media communication session between the calling party and the called party via the determined communication route.

Methods and apparatus are disclosed for reducing wireless telecommunication costs for enterprises having a plurality of PBX-equipped sites, connected by either a public network (e.g., the PSTN, the Internet, etc.), a private network (e.g., leased lines, a virtual private network [VPN] over the Internet, etc.), or some combination of public and private networks. In particular, the illustrative embodiments of the present invention attempt to reduce telecommunication costs by advantageously routing calls from an off-premises wireless terminal belonging to the enterprise via one or more of the enterprise's private branch exchanges. The present invention is especially advantageous in that it can reduce telecommunication costs for calls from an off-premises wireless terminal to any type of destination: another cell phone, a wireline terminal, a private branch exchange, etc.

A recovery network may provide communication recovery and backup services to an organization. The organization may comprise an internal network, such as Internet Protocol (IP) network. An alternative communication path communicatively couples communication devices of the organization to a public communication network. A recovery application operates on devices of the organization. The recovery network receives periodic availability indicators from devices within the organization. The recovery network identifies a communication endpoint of the intended recipient of a communication request using the availability indicators.
