AAR Group Choose the automated alternate routing (AAR) group for this device.
The AAR group provides the prefix digits that are used to route calls
that are otherwise blocked due to insufficient bandwidth. An AAR
group setting of None specifies that no rerouting of blocked calls will
be attempted.
Tunneled Protocol Choose the QSIG option if you want to use H.323 gateways to
transport (tunnel) non-H.323 protocol information in H.323 signaling
messages from Cisco Unified Communications Manager to other
Annex M.1-compliant H.323 PINXs. QSIG tunneling supports the
following features: Call Completion, Call Diversion, Call Transfer,
Identification Services, Message Waiting Indication, and Path
Replacement.
Note Refer to the Cisco Unified Communications Manager
Compatibility Matrix for information about Annex M.1 feature
compatibility with third-party vendor(s).
QSIG Variant To display the options in the QSIG Variant drop-down list box, choose
QSIG from the Tunneled Protocol drop-down list box.
This parameter specifies the protocol profile that is sent in outbound
QSIG facility information elements.
From the drop-down list box, choose one of the following options.
Keep this parameter set to the default value unless a Cisco support
engineer instructs otherwise.
• No Changes
• Not Selected
• ECMA—If the QSIG Variant is set to ECMA (Protocol Profile
0x91), ensure that the ASN.1 Rose OID Encoding service
parameter is set to Use Global Value (ECMA).
• ISO—(Default) If the QSIG Variant is set to ISO (Protocol Profile
0x9F), ensure that the ASN.1 Rose OID Encoding service
parameter is set to either Use Local Value or Use Global Value
(ISO).
For more information, see the following information:
• Be aware that the QSIG Variant can also be defined as a
clusterwide parameter. For more information, refer to
Chapter 25,
“Service Parameters Configuration.”
• For information on QSIG support with Cisco Unified
Communications Manager, refer to
“Q.Signaling (QSIG)” in the
“Understanding IP Telephony Protocols” chapter of the Cisco
Unified Communications Manager System Guide.
