Version 5.8
Defines the maximum gap between two SID frames when using
the EVRC voice activity detector. Units are in EVRC frame size
(20 msec).
The range is 0 to 20000. The default value is 32.
Note: Supported for EVRC and EVRC-B coders.
Determines the DSP template to use on the device. Each DSP
template supports specific coders, channel capacity, and features.
For the list of supported DSP templates, refer to the device's
Release Notes.
The default is DSP template 0.
You can load different DSP templates to analog and digital
modules, using the syntax DSPVersionTemplateNumber=xy,
where:

x = 0 or 1 for DSP templates of analog modules

y = 0 to 5 for DSP templates of digital and MPM modules
Note: For this parameter to take effect, a device reset is required.
This ini file table parameter allows the device to use a
combination of up to two DSP templates and determines the
percentage of DSP resources allocated per DSP template. The
DSP templates' values and capabilities (i.e., supported coders,
channel capacity, and features) are specified in the device's
Release Notes.
The format of this table is as follows:
[DspTemplates]
FORMAT DspTemplates_Index =
DspTemplates_DspTemplateNumber,
DspTemplates_DspResourcesPercentage;
[\DspTemplates]
For example, to load DSP Template 1 to 50% of the DSPs, and
DSP Template 2 to the remaining 50%, the table is configured as
follows:
DspTemplates 0 = 1, 50;
DspTemplates 1 = 2, 50;
Note: The ini file parameter DSPVersionTemplateNumber is
ignored when using the parameters specified in this table.
Defines the format of the RTP header for VBR coders.

[0] = Payload only (no header, no TOC, no m-factor) - similar
to RFC 3558 Header Free format (default).

[1] = Supports RFC 2658 - 1 byte for interleaving header
(always 0), TOC, no m-factor.

[2] = Payload including TOC only, allow m-factor.

[3] = RFC 3558 Interleave/Bundled format.
Determines the required number of silence frames at the
beginning of each silence period, when using the VBR Coder
silence suppression.
The range is 0 to 255. The default value is 1.
