In one embodiment, a system identifies an Internet Protocol (IP) device as a calling party for calls from either a Voice over Internet Protocol (VoIP) portion or a cellular portion of a multi-protocol phone. As a result, return calls to the multi-protocol phone are always sent through an IP device to allow call handling or Single Number Reach (SNR) functionality for the return calls.

Call identification mechanism for multi-protocol telephones

An embodiment may include an apparatus comprising a dejitter buffer to receive packets containing audio data, a codec coupled with the dejitter buffer, the codec to receive coded audio frames from the dejitter buffer and decode them, and a concealed seconds meter coupled with the dejitter buffer, the concealed seconds meter to record concealment events by the decoder to provide an objective measure of media impairment. Another exemplary embodiment may be a method comprising receiving packets containing audio information at a dejitter buffer, decomposing the packets to coded audio frames, sending the coded audio frames to a decoder and decoding the frames, generating a concealment output stream if the decoder does not receive a valid frame from the dejitter buffer, and recording concealment events to provide an objective measure of media impairment.
