摘要：A radio telecommunications network for providing redundant interfaces from amobile switching center (MSC) to an associated voice mail system (VMS) is disclosed. Theradio telecommunications network includes a first peripheral equipment gateway (PEG-1)connected to the VMS, wherein the PEG-1 provides a first interface between the VMS andthe radio telecommunications network, and a second peripheral equipment gateway(PEG-2) connected to the VMS, wherein the PEG-2 provides a second interface betweenthe VMS and the radio telecommunications network. The MSC receives and routes anincoming call from a mobile station requesting voice mail retrieval, and a home locationregister (HLR) simultaneously sends routing request messages to PEG-1 and PEG-2, andincludes an indication that the routing request messages are for voice mail retrieval. PEG-1 and PEG-2 return routing numbers for the VMS to the HLR. The HLR receives at leastone routing number for the VMS, and the MSC delivers the incoming call to the VMSutilizing the first routing number received in the HLR.
