Version 7.2 1103 Mediant 1000B Gateway & E-SBC
User's Manual 62. Configuration Parameters Reference
Parameter Description

 [1] Enable = Enables ISDN call rerouting. When the device sends
the INVITE message to the remote SIP entity and receives a SIP
302 response with a Contact header containing a URI host name
that is the same as the device's IP address, the device sends a
Facility message with a Call Rerouting invoke method to the ISDN
and waits for the PSTN side to disconnect the call.
Note: When the parameter is enabled, ensure that you configure in
the IP-to-Tel Routing table (PSTNPrefix ini file parameter) a rule to
route the redirected call (using the user part from the 302 Contact
header) to the same Trunk Group from where the incoming Tel-to-IP
call was received.
[EnableCIC] Enables the relay of the Carrier Identification Code (CIC) to the ISDN.
 [0] = (Default) Disabled - CIC is not relayed to the ISDN.
 [1] = Enabled - CIC (received in the INVITE Request-URI) is
relayed to the ISDN in the Transit Network Selection (TNS) IE of
the Setup message. For example: INVITE
sip:555666;cic=2345@100.2.3.4 sip/2.0.
Note:
 This feature is supported only for SIP-to-ISDN calls.
 The parameter AddCicAsPrefix can be used to add the CIC as a
prefix to the destination phone number for routing IP-to-Tel calls.

Add IE in SETUP
add-ie-in-setup
[AddIEinSetup]
Global parameter that defines an optional Information Element (IE)
data (in hex format) to add to ISDN Setup messages. You can also
configure this functionality per specific calls, using IP Profiles
(IpProfile_AddIEInSetup). For a detailed description of the parameter
and for configuring this functionality in the IP Profiles table, see
''Configuring IP Profiles'' on page 393.
Note: If this functionality is configured for a specific IP Profile, the
settings of this global parameter is ignored for calls associated with
the IP Profile.
Trunk Groups to Send IE
trkgrps-to-snd-ie
[SendIEonTG]
Defines Trunk Group IDs (up to 50 characters) from where the
optional ISDN IE (defined by the parameter AddIEinSetup) is sent.
For example: '1,2,4,10,12,6'.
Note:
 You can configure different IE data for Trunk Groups by defining
the parameter for different IP Profile IDs (using the parameter
IPProfile), and then assigning the required IP Profile ID in the IP-
to-Tel Routing table (PSTNPrefix).
 When IP Profiles are used for configuring different IE data for
Trunk Groups, the parameter is ignored.
Enable User-to-User IE for
Tel to IP
Enables transfer of User-to-User (UU) IE from ISDN to SIP.

Disable (default)
