Methods, systems, and machine-readable media are disclosed for initiating communications between entities operating in disparate environments and/or with different base protocols. According to one embodiment, a method for initiating a communication can comprise receiving a request from the first entity to initiate communications. An initiation message can be generated and formatted in a base protocol of the second entity. The base protocol of the second entity can be different from a base protocol of the first entity. The initiation message can be sent to the second entity to cause the second entity to initiate communications with a third entity in the base protocol of the second entity.
