A wireless telephone system comprising a base unit coupleable to one or more external telephone lines and having a base transceiver, and at least one wireless handset. The wireless handset has a handset transceiver for establishing a digital link with the base unit via the base transceiver over a wireless channel, wherein the handset and base unit communicate via the digital link by fixed-size audio packets comprising a plurality of audio data samples and a plurality of error correction bits. Qualities of the digital link are monitored to determine whether a change in error rate occurs. In response to the determination, a packet structure of subsequent audio packets is changed from a first packet structure to a second packet structure to change the relative number of bits devoted to audio data samples and to error correction bits.
