The receiver is configured to receive an input signal in a first encoding format. The input signal has an input payload. The first encoding format is a dual-mode InterSystem Link Protocol (ISLP)/Enhanced Variable Rate Coding (EVRC) codec. The apparatus further comprises a transcoder operatively coupled to the receiver. The transcoder is structured to transcode in a single channel the first encoding format to a second encoding format. The transcoder is configured to generate an output signal in the second encoding format for transmission over an internet protocol (IP) network to a second mobile switching center based on the input signal. The output signal has an output payload based on the input payload. The transcoder is configured to switch between a default voice handling mode for the EVRC codec and a clear channel mode for the ISLP codec to form the output payload."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Single channel EVRCx, ISLP and G.711 transcoding in packet networks","description":"An apparatus in one example comprises a receiver of a first mobile switching center.
