44.1.4 Prerecorded Tones File

The Prerecorded Tone (PRT) is a .dat file containing a set of prerecorded tones that can be
played by the device. For example, it can be used to play music on hold (MoH) to a call
party that has been put on hold. Up to 40 tones (totaling approximately 10 minutes) can be
stored in a single PRT file on the device's flash memory. Play of tones from a PRT file is
supported for Gateway and SBC calls.
The PRT file overcomes the limitations of the CPT file such as limited number of
predefined tones and limited number of frequency integrations in one tone. If a specific
prerecorded tone exists in the PRT file, it overrides the same tone that exists in the CPT
file, and is played instead.
You can define a PRT file for SBC calls with multiple tones of the same tone type but with
different coders. If one of the tones is defined with the same coder as used in the current
call, the device always selects it in order to eliminate the need for using DSP resources. If
the coder of the tone is the same as that of the call, DSPs are not required; if they are
different, DSPs are required.
