1. A telecommunications system for redirecting in-band control of signaling, comprising:

  • a network switch for routing a call from a calling party to an other party, said call having an inbound leg from said calling party to said network switch and an outbound leg from said network switch to said other party;

    call routing control circuitry, operably connected to said network switch, for controlling said network switch in response to in-band control signals received from said inbound and outbound legs; and

    call control redirection circuitry, operably connected to said network switch and said call routing control circuitry, for monitoring said inbound and outbound legs for an activating in-band signal, directing said network switch to separate said inbound leg from said outbound leg in response to detecting said activating in-band signal, directing said call routing control circuitry to respond to in-band control signals received from said outbound leg after said separation, and directing said network switch to ignore any in-band control signals received from said inbound leg after said separation.
