early-media
[TelProfile_EnableEarlyMedia]
Enables the Early Media feature, which sends media (e.g.,
ringing) before the call is established.
 [0] Disable (default)
 [1] Enable

Digital: The device sends a SIP 18x response with
SDP, allowing the media stream to be established
before the call is answered.

Analog: The device sends a SIP 183 Session
Progress response with SDP instead of a 180 Ringing,
allowing the media stream to be established before
the call is answered.
Note:
 Digital: The inclusion of the SDP in the 18x response
depends on the ISDN Progress Indicator (PI). The SDP is
sent only if PI is set to 1 or 8 in the received Proceeding,
Alerting, or Progress messages. See also the
ProgressIndicator2IP parameter, which if set to 1 or 8, the
device behaves as if it received the ISDN messages with
the PI.

ISDN: Sending a 183 response depends on the ISDN
PI. It is sent only if PI is set to 1 or 8 in the received
Proceeding or Alerting messages. Sending 183
response also depends on the
