At a multi-tenant communication platform, and responsive to authentication of a communication request provided by an external system, a routing address record of the communication platform is determined that matches a communication destination of the communication request. The matching routing address record associates the communication destination with a plurality of external communication providers. At least one communication provider associated with the matching routing address record is selected, and a request to establish communication with the communication destination is provided to each selected communication provider. The communication request specifies the communication destination and account information. ## Claims ### Claim 1 A method comprising: maintaining a set of routing options of at least two external communication providers using different transport protocols, which comprises of creating routing option records of a communication destination for a plurality of transport protocols, where a routing option record maps a communication destination to a destination endpoint;
