What is Automatic Location-Based Routing (ALBR)?

ALBR intelligently minimizes latency in your voice calls by automatically routing the media path through the closest voice gateway for both inbound and outbound calls without manual configuration.

Unlike other providers, you do not need to select the Vonage API gateway you want to send your SIP traffic through, depending on its location to your servers. You send all of your SIP traffic to and Vonage will take care of routing it through the lowest latency gateway, optimizing the media path.

How does ALBR work, and what does this mean for my voice capabilities?

With ALBR, outbound calls are automatically routed to the closest voice gateway based on the source IP address of the request. Similarly, inbound calls from a Vonage number that are configured to be forwarded to SIP URIs (e.g., via the Vonage API account dashboard), will be routed to the closest voice geographic gateway resolved to that SIP URI. This is all done automatically, increasing call quality and significantly lowering latency.
