1. An apparatus comprising:
- a network interface configured to receive, via a circuit-switched network and during a first time period, a packet that includes primary coding of a first audio frame, redundant coding of a second audio frame, and one or more bits that indicate signaling information, the signaling information indicating which of the primary coding or the redundant coding is to be decoded, the circuit-switched network associated with communication of audio frames to devices during fixed time intervals;
a processor configured to determine the signaling information based on the one or more bits and to initiate an audio output based on the decoded primary coding or the decoded redundant coding;
a pre-redundancy buffer configured to store a portion of the packet; and
a decoder configured to decode the primary coding or the redundant coding based on the signaling information.

Abstract
An apparatus includes a network interface configured to receive, via a circuit-switched network, a packet. The packet includes a primary coding of a first audio frame, redundant coding of a second audio frame, and one or more bits that indicate signaling information. The signaling information corresponds to a decode operation of at least one of the primary coding or the redundant coding. The apparatus further includes a decoder configured to decode a portion of the packet based on the signaling information.
