User's Manual
Determines the format of the RTP header for VBR coders.

[0] = (Default) Payload only (no header, TOC, or m-factor) -
similar to RFC 3558 Header Free format.

[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.
Defines 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 is 1.
Determines the payload format of the AMR header.

[0] = Non-standard multiple frames packing in a single RTP
frame. Each frame has a CMR and TOC header.

[1] = AMR frame according to RFC 3267 bundling.

[2] = AMR frame according to RFC 3267 interleaving.

[3] = AMR is passed using the AMR IF2 format.
Note: Bandwidth Efficient mode is not supported; the mode is
always Octet-aligned.
Determines the DSP template used by the device. Each DSP
template supports specific coders, channel capacity, and features.
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
Notes:

For this parameter to take effect, a device reset is required.

For a list of supported DSP templates, see DSP Templates.
Table 51-36: DTMF Parameters
Determines the DTMF transport type.

[0] Mute DTMF = DTMF digits are removed from the voice
stream and are not relayed to remote side.

[2] Transparent DTMF = DTMF digits remain in the voice
stream.

[3] RFC 2833 Relay DTMF = (Default) DTMF digits are removed
from the voice stream and are relayed to remote side according
to RFC 2833.

[7] RFC 2833 Relay Decoder Mute = DTMF digits are sent
according to RFC 2833 and muted when received.
