Version 6.6
The range is 0 to 20000. The default is 12.
Note: Supported for EVRC and EVRC-B coders.
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 is 32.
Note: This parameter is applicable only to EVRC and EVRC-B
coders.
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.
Defines the AMR payload format type.

[0] Bandwidth Efficient

[1] Octet Aligned (default)
Table ‎ 5 1-34: 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: This parameter is automatically updated if the parameters
TxDTMFOption or RxDTMFOption are configured.
Defines the DTMF gain control value (in decibels) to the PSTN or
analog side.
The valid range is -31 to 0 dB. The default is -11 dB.
Note: This parameter can also be configured in a Tel Profile.
Defines the range (in decibels) between the high and low frequency
