Configuring LI on I-SBC using the EMA GUI

This section outlines how to configure the I-SBC LI using the EMA Calea user account. This I-SBC configuration procedure also applies to hardware SBCs.

If you have an SBC system with access to the PSX and EMS, refer to Creating and Activating LI Configuration for I-SBC to configure the I-SBC LI through the EMS.

Configuring CDC

As a Calea user, you can configure the LI of an I-SBC in the EMA.

To Create a CDC for the I-SBC

Use the following procedure to create a CDC for the default or IMS LI of an I-SBC.

1. Log into the I-SBC EMA as a Calea user.
2. Select Configuration > Intercept > Call Data Channel.
3. Select default from the Address Context drop-down menu. You can configure the LI only with the default Address Context.
4. Click New Call Data Channel.
5. Configure the Create New Call Data Channel panel for either the default or IMS LI. For descriptions of the parameters in the following tables, refer to Intercept - Call Data Channel.

   • To configure the CDC for the default LI, use the following table.  

     Note

     You cannot create or modify mediation servers for an I-SBC with a default LI. Since you cannot create mediation servers, you cannot configure the signaling interception, media TCP, or media UDP for a default LI.

     For I-SBCs with a default LI, you can configure only the CDC. In the CDC configuration, you provide the IP Address and Port details.

4. Select the CDC you created for the I-SBC from the Call Data Channel drop-down menu.

5. Click New Mediation Server.

   Create new Mediation Server

   

6. In the Mediation Server field, enter a mediation server name.

7. Click Save.

8. Click Ok.

   Note

   You can repeat this procedure to create a maximum of eight mediation servers for the I-SBC.

Configuring Signaling Interception

This section outlines how to configure the signaling interception.
