Description
✔
Analog: For IP-to-Tel calls, if the
EnableEarlyMedia parameter is set to 1, the device
sends a 183 Session Progress message with SDP
immediately after a call is placed to the analog line.
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.
Analog: Enables the Call Hold feature, which allows users,
connected to the device, to place a call on hold (or remove
from hold), using the phone's Hook Flash button.
Digital: Enables the interworking of the Hold/Retrieve
supplementary service from ISDN to SIP .
■ [0] Disable
■ [1] Enable (default)
Note:
■ Digital interfaces: To interwork the Hold/Retrieve
supplementary service from SIP to ISDN (QSIG and
Euro ISDN), set the EnableHold2ISDN parameter to 1.
■ Analog interfaces: To use the call hold service, the
devices at both ends must support this option.
■ The corresponding global parameter is EnableHold.
Defines an optional Information Element (IE) data (in hex
format) which is added to ISDN Setup messages. For
example, to add IE '0x20,0x02,0x00,0xe1', enter the value
"200200e1".
Note:
■ The parameter is applicable only to digital interfaces.
■ The IE is sent from the Trunk Group IDs configured by
the SendIEonTG parameter.
■ You can configure different IE data for Trunk Groups by
configuring the parameter for different IP Profiles and
then assigning the required IP Profile in the IP-to-Tel
Routing table (PSTNPrefix).
