|
accessClass | N/A | Set parameter to " Unable to show "metadata-from": No such page "_space_variables" validates Source IP Address against Via header IP Address and transparently passes UEs Via header in egress messages towards network entities. If REGISTER message is received with "sec-agree" in Proxy-Require header along with Auth headers, and no IP Sec profile is configured, the Unable to show "metadata-from": No such page "_space_variables" rejects the message with "4xx Bad Extension" error response irrespective of the accessClass parameter value.When GIBA security mechanism is selected and Via header is configured to pass transparently to egress leg, Unable to show "metadata-from": No such page "_space_variables" inserts a “received” parameter with the source IP address of the PDU if the host portion of the UE’s Via header does not equate to the source IP address seen by the Unable to show "metadata-from": No such page "_space_variables" .
|
allowByeChallenge | N/A | This flag enables the Bye-Challenge feature. When this flag is enabled, the BYE's might get challenged either by 401 or 407 and the call is released only when the BYE with appropriate credentials are received.

| N/A | Enable this flag to use CCF received in PCFA as CDF.
|
| N/A | Enable this flag to allow the usage of different IP-Port as contact for each active registration towards Cisco Unified Communication Manager (CUCM). The SBC uses either an independent media port range configured per IP Trunk Group (IPTG), or a new port from the system-wide media port range if no independent media port range is configured per IPTG.
The SBC supports this feature when: Disable usePortRangeFlag flag before performing the Live Software Upgrade (LSWU). Feature limitations and restrictions: This feature is supported only for UDP.
