Abstract

A system and method that includes receiving a communication request of an account, the communication request including communication properties; identifying at least two routing options of a route priority list, the routing options capable of completing the communication request and identified according to a priority heuristic; generating a communication cost from the communication properties; and upon receipt of the routing response and the communication cost response, executing a communication with a routing option of the routing priority list and committing a cost of the communication to the account.

Claims

1. A method comprising:

receiving a communication request of an account, the request including a maximum cost parameter and a set of communication properties including at least a destination endpoint;

compiling a route priority list of routing option according to the communication properties of the communication request;

delivering the route priority list to a communication service;

querying a communication cost according to the communication properties;

delivering the communication cost to a communication service; and

at the communication service, if the communication cost complies with the maximum cost parameter, selecting a routing option of the route priority list and establishing a communication through the selected routing option and committing the communication cost to the account; and

at the communication service, if the communication cost does not comply, alerting an account resource of a communication failure.

2. The method of claim 1, wherein alerting an account resource comprises responding to the communication request with a communication failure message.

3. The method of claim 2, wherein the communication failure message includes alternative routing options;

further comprising receiving a message that specifies a selection of an alternative routing option; and

establishing a communication through the selected alternative routing option.

4. The method of claim 1, wherein alerting an account resource comprises transmitting an application transport message to a callback universal resource identifier (URI).

5. The method of claim 1, wherein a first routing option of the route priority list is communication over a first transport protocol and a second routing option of the route priority list is communication over a second transport protocol.

6. The method of claim 5, wherein establishing a communication through the selected routing option comprises transforming content of the communication properties to a format compatible with a transport protocol of the selected routing option.

7. The method of claim 1, wherein identifying at least two routing options according to a priority heuristic comprises analyzing intended communication content and identifying routing options with transport capabilities of delivering intended communication content to the destination endpoint.

8. The method of claim 7, further comprising calculating an effective internal cost of communicating intended communication content of the communication properties;

and prioritizing routing options of the route priority list in part according to the effective internal cost of the routing options.
