Management Protocol
Web INI SNMP EMS CLI
This feature provides support for configuring a default redirect reason for Tel-to-IP
calls. This is configured by the new parameter, Tel2IPDefaultRedirectReason.
The device includes this default redirect reason in the SIP History-Info header of the
outgoing INVITE if the received Q931 ISDN Setup message does not include a
redirect reason or includes only an “unknown” reason. If a redirect reason exists in the
received Setup message, the new parameter is ignored and the device sends the
INVITE message with the reason according to the received Setup message. If the
parameter is not configured, the outgoing INVITE is sent with the redirect reason (if
none or “unknown” then no reason) as received in the Setup message.
45. UC Namespace for MLPP Calls:
Product

Mediant 600 Mediant 1000
Mediant 800 MSBG Mediant 1000 MSBG

Mediant 3000/TP-6310 Mediant 3000 HA/TP-6310
Mediant 3000/TP-8410 Mediant 3000 HA/TP-8410
Management Protocol
Web INI SNMP EMS CLI
This feature provides support for configuring a new default namespace, “UC” for Multi-
Level Precedence & Preemption (MLPP) calls received from the ISDN side and
destined for the Application server. This is configured by setting the existing parameter
MLPPDefaultNamespace to the new option, “UC” (5). The namespace value is not
present in the Precedence IE of the PRI Setup message. Therefore, this value is used
in the Resource-Priority header of the outgoing SIP INVITE request.
