Internet network e.g. session initiation protocol network, fallback assisting device, has mapping functionality that assigns bandwidths to data and audio codecs during reception of codecs, and bandwidth of data/audio codec during reception

摘要

The device has mapping functionality, which assigns a bandwidth to a data codec e.g. VIDEO codec, and another bandwidth to an audio codec during reception of data and audio codecs. The mapping functionality assigns the bandwidth of the data or audio codec during reception, where the bandwidth of the data codec is greater than the bandwidth of the audio codec. The device provides assisting of a communication between two terminals that are designed as integrated services digital network (ISDN)-/or plain old telephone services (POTS)-/or session initiation protocol (SIP)-terminals.
