Abstract: Arrangements (e.g., apparatus, method, machine-readable medium, chipset, etc.) guiding selection of a gateway to which to present a hand-off request for an outgoing communication session, including: referencing a gateway database storing gateway data for gateways of plural communication carriers, respectively, the gateway data of each subject gateway including an IP address and at least one connection efficiency value for the subject gateway; and considering connection efficiency values of ones of the gateways of the plural communication carriers in the gateway database according to a predetermined selection criteria, to form an output instruction which guides selection of at least one gateway to which to present the hand-off request.

Abstract: Techniques are disclosed for troubleshooting an IP telecommunications network. A network server sends a notification message to a plurality of IP addresses each associated with a customer endpoint. The server receives a notification response from each of the customer endpoint IP addresses and determines a response time for each of the customer endpoint IP addresses. The response times are compared to an expected notification response time and those that exceeded an expected response time are geo-located. Traceroutes are performed to customer endpoint IP addresses in the same geo-located area that exceeded the expected response time. All hops between the server and the customer endpoint IP addresses for each traceroute performed are geo-coded to determine impacted and non-impacted routes between the server and each customer endpoint IP address. IP traffic between the server and a customer endpoint IP address may then be re-routed from an impacted route to a non-impacted route.
