ABSTRACT:
A radio telecommunications network for providing redundant interfaces from a mobile switching center (MSC) to an associated voice mail system (VMS) is disclosed. The radio 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 and the radio telecommunications network, and a second peripheral equipment gateway (PEG-2) connected to the VMS, wherein the PEG-2 provides a second interface between the VMS and the radio telecommunications network. The MSC receives and routes an incoming call from a mobile station requesting voice mail retrieval, and a home location register (HLR) simultaneously sends routing request messages to PEG-1 and PEG-2, and includes 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 least one routing number for the VMS, and the MSC delivers the incoming call to the VMS utilizing the first routing number received in the HLR.
