The

Spacevars
0series4
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 

Spacevars
0product
supports up to 500 simultaneous LI sessions. 
Spacevars
0product
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 
Spacevars
0product
routes the call as directed and additionally reports call events to the IS.

The 

Spacevars
0product
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).

Note
You must use the default addressContext when configuring LI.

See Lawful Intercept page for an in-depth explanation of LI functionality.

Note
When configuring LI through EMA/ERE, you must be 'Calea' user. See Managing Default Accounts and PasswordsSBC Core Users and Accounts for descriptions of users and permissions.
