The following are the typical types of media processing which DSPs are designed to carry out:

Coding: The process of converting TDM voice to packetized voice using CODECs such as G.711, G.729, etc.

Transcoding: The process of converting from one CODEC stream to another.  For example a G.711 codec voice stream converted to a G.729 codec stream.

Conferencing: The process of mixing multiple voice streams over one voice path.

Media Termination Point (MTP): The process of terminating a voice stream for the purpose of carrying out functions such as ‘hold’, ‘transferring’, or ‘conferencing’ features by an end-user phone.
