A system and method are provided with a computing system, capable of binding SMS, voice and other media transactions into a continuous, stateful messaging process that maintains awareness of the communications event over time delays and media transitions. Communications events between two or more communicators over one communications medium are bridged by the system to a second communications medium, according to the needs of the communicators. Various applications of the system permit selective or automated bridging of the communications event based on predetermined events and timeline formulae.
