Method of routing calls to peripheral devices

摘要

A method of the present invention includes an MSC (101) receiving (201) a request for a call. A call routing request indicating that no peripheral device interaction has taken place on the call is forwarded (203) to an HLR or home location register (107). The MSC receives (205) call routing instructions that direct the call to a peripheral device (109). The call is routed (211) to the peripheral device (109). The peripheral device (109) performs (213) a function for the call and routes (215) the call to the MSC. A message requesting call routing instructions and identifying the peripheral device is forwarded (203) to the HLR.
