Mediant 800B Gateway & E-SBC
Parameter Description
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.
Hold
enable-hold
[IpProfile_EnableHold]
Enables the Call Hold feature (analog interfaces) and interworking of
the Hold/Retrieve supplementary service from ISDN to SIP (digital
interfaces). For analog: The Call Hold feature allows users, connected
to the device, to place a call on hold (or remove from hold), using the
phone's Hook Flash button.
 [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.
Add IE In Setup
add-ie-in-setup
[IpProfile_AddIEInSetup]
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).
 The feature is similar to that of the EnableISDNTunnelingIP2Tel
parameter. If both parameters are configured, the
EnableISDNTunnelingIP2Tel parameter takes precedence.
 The corresponding global parameter is AddIEinSetup.
QSIG Tunneling
enable-qsig-tunneling
[IpProfile_EnableQSIGTunn
eling]
Enables QSIG tunneling-over-SIP for this SIP entity. This is according
to IETF Internet-Draft draft-elwell-sipping-qsig-tunnel-03 and ECMA-
355 and ETSI TS 102 345.
 [0] Disable (default).
 [1] Enable = Enables QSIG tunneling from QSIG to SIP, and vice
versa. All QSIG messages are sent as raw data in corresponding
SIP messages using a dedicated message body.
Note:
 The parameter is applicable only to digital interfaces.
 QSIG tunneling must be enabled on originating and terminating
devices.
 To enable this function, set the ISDNDuplicateQ931BuffMode
parameter to 128 (i.e., duplicate all messages).
