Tel Profile Parameter Global Parameter
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

cancellation.

[0] Adaptive NLP = (Default) NLP adapts according to
echo changes

[1] Disable NLP
