Abstract:
1. A computer-implemented method, comprising: receiving an indication that a destination user agent identifier was ported from a first service provider to a second service provider, wherein the indication is from the first service provider, wherein the indication results from querying the first service provider for a previous session and receiving the indication from the first service provider in response to the querying; receiving a request to establish a session between an origination user agent and a destination user agent, the request comprising the destination user agent identifier, wherein the origination user agent is associated with at least one Internet Protocol version 6 (IPv6) network and the destination user agent is associated with at least one non-IPv6 network; using one or more computer processors, determining that the destination user agent identifier was ported from the first service provider to the second service provider based on the indication from the first service provider; and providing routing information for establishing the session from the origination user agent to the destination user agent through the second service provider rather than through the first service provider, wherein the session is established over one or more Internet protocol networks.
