The
Unable to show "metadata-from": No such page "_space_variables"
provides Lawful Intercept (LI) support using one of two methods:- Using ERE with provisioning support from EMA (license required).
- Using centralized PSX with provisioning support from EMS (license required).
The
Unable to show "metadata-from": No such page "_space_variables"
supports up to 500 simultaneous LI sessions. Unable to show "metadata-from": No such page "_space_variables"
works in coordination with an Intercept Server (IS) to provide call data and call content to law enforcement agencies for calls involving identified intercept subjects. When it receives matching LI criteria in a policy response from ERE (or external PSX in centralized PSX solution), the Unable to show "metadata-from": No such page "_space_variables"
routes the call as directed and additionally reports call events to the IS.The
Unable to show "metadata-from": No such page "_space_variables"
also sends an RTP copy of the call's voice streams (call content) to an IP address provided by the IS. LI is configured by EMA (or EMS in centralized PSX solution). The target number is uploaded to LI table of ERE (or PSX, with the help of EMS).When configuring LI through EMA/ERE, you must be "Calea" user. See Managing SBC Core Users and Accounts for descriptions of users and permissions.
You can configure the LI using only the default Address Context.
Note
The SBC 7000 system supports creating IP Interface Groups containing sets of IP interfaces that are not "processor friendly" (i.e. carried on physical Ethernet ports served by separate processors). However, restrictions exist regarding the usage of such Interface Groups.
(This ability does not apply to the SBC 5400 system which have only two physical media ports. IP interfaces from the two physical ports may be configured within the same IP Interface Groups without restrictions.)
For complete details, refer to Configuring IP Interface Groups and Interfaces.
See Lawful Intercept page for an in-depth explanation of LI functionality.
The Intercept object can be viewed as "Calea" user. For more information, refer to Users and Application Management - User and Session Management.
The Intercept can be checked for default Address Context. Use the drop-down box to select the default Address Context.
