Parameter Description
[TelProfile_IPDiffServ] The valid range is 0 to 63. The default is 46.
Note:
■ For more information on DiffServ, see Configuring
Class-of-Service QoS.
■ The corresponding global parameter is Premi-
umServiceClassMediaDiffServ.
'Signaling DiffServ'
signaling-diffserv
[TelProfile_SigIPDiffServ]
Defines the DiffServ value for Premium Control CoS
content (Call Control applications).
The valid range is 0 to 63. The default is 40.
Note:
■ For more information on DiffServ, see Configuring
Class-of-Service QoS.
■ The corresponding global parameter is Premi-
umServiceClassControlDiffServ.
'Enable Early Media'
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.
✔ CAS: See the ProgressIndicator2IP parameter.
✔ 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
ReleaseIP2ISDNCallOnProgressWithCause
parameter, which must be set to any value other
than 2.
■ Digital: See also the IgnoreAlertAfterEarlyMedia
parameter. The parameter allows, for example, to
interwork Alert with PI to SIP 183 with SDP instead of
180 with SDP.
