SIP MLT Codec Settings
SIP MLT's can use various CODECs. A CODEC is a standard for converting an analogue signal to digital.
This conversion process is handled by the DSP (Digital Signal Processors) on the GPZ-IPLE card.
Each CODEC has different voice quality and compression properties. The correct choice of CODEC will be
based on the amount of bandwidth available, the amount of calls required and the voice quality required.
