User's Manual
Defines the AMR payload format type.

[0] Bandwidth Efficient

[1] Octet Aligned (default)
Note: The AMR payload type can also be configured per Coder
Group (see Configuring Coder Groups on page 390). The Coder
Group configuration overrides the parameter.
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.
Table 61-37: 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.
Note: The parameter is automatically updated if the parameters
FirstTxDTMFOption or RxDTMFOption are configured.
Defines the DTMF gain control value (in decibels) to the Tel side.
The valid range is -31 to 0 dB. The default is -11 dB.
Note: The parameter can also be configured in a Tel Profile.
Defines the range (in decibels) between the high and low frequency
components in the DTMF signal. Positive decibel values cause the
higher frequency component to be stronger than the lower one.
Negative values cause the opposite effect. For any parameter
value, both components change so that their average is constant.
The valid range is -10 to 10 dB. The default is 0 dB.
Note: For the parameter to take effect, a device reset is required.
Defines the time (in msec) between generated DTMF digits to the
Tel side (if FirstTxDTMFOption = 1, 2 or 3).
The valid range is 0 to 32767. The default is 100.
