Tel Profile Parameter Global Parameter
placed to a phone/PBX. This is used to cut-through the
voice path before the remote party answers the call. This
allows the originating party to listen to network call
progress tones such as ringback tone or other network
announcements.
Digital: For IP-to-Tel calls, if the parameter
EnableEarlyMedia is set to 1, the device sends 180
Ringing with SDP in response to an ISDN Alerting or it
sends a 183 Session Progress message with SDP in
response to only the first received ISDN Proceeding or
Progress message after a call is placed to PBX/PSTN
over the trunk.
[8] PI = 8: same as PI = 1.
Note: The corresponding global parameter is
ProgressIndicator2IP.
Echo Canceler
Echo Canceler
echo-canceller
[TelProfile_EnableEC]
Enables the device's Echo Cancellation feature (i.e., echo from
voice calls is removed).
[0] Disable
[1] Line Echo Canceller (default)
For more information on echo cancellation, see ''Configuring
Echo Cancellation'' on page 187.
Note: The corresponding global parameter is
EnableEchoCanceller.
EC NLP Mode
echo-canceller-nlp-mode
[TelProfile_ECNlpMode]
Enables Non-Linear Processing (NLP) mode for echo
cancellation.
[0] Adaptive NLP = (Default) NLP adapts according to echo
changes
[1] Disable NLP
Note: The corresponding global parameter is ECNLPMode.
Jitter Buffer
Dynamic Jitter Buffer Minimum Delay
jitter-buffer-minimum-delay
[TelProfile_JitterBufMinDelay]
Defines the minimum delay (in msec) of the device's dynamic
Jitter Buffer.
The valid range is 0 to 150. The default delay is 10.
For more information on Jitter Buffer, see ''Configuring the
Dynamic Jitter Buffer'' on page 199.
Note: The corresponding global parameter is DJBufMinDelay.
Dynamic Jitter Buffer Maximum Delay
jitter-buffer-maximum-
delay
[TelProfile_JitterBufMaxDelay]
Defines the maximum delay (in msec) for the device's Dynamic
Jitter Buffer.
The default is 300.
Dynamic Jitter Buffer Optimization Factor
jitter-buffer-optimization-factor
[TelProfile_JitterBufOptFactor]
Defines the Dynamic Jitter Buffer frame error/delay optimization
factor.
The valid range is 0 to 12. The default factor is 10.
For more information on Jitter Buffer, see ''Configuring the
Dynamic Jitter Buffer'' on page 199.
Note:
For data (fax and modem) calls, configure the parameter to
