Configuring Realm Groups

   ORACLE(configure)# media-manager
   ORACLE(media-manager)#

3. Type realm-group and press Enter.

   ORACLE(realm-group)#

4. name—Enter the name of the realm group.
5. source-realm—Enter the list of one or more global/SIP realms that you want to designate as source realms for the purpose of blocking early media; this is the realm identifier value for the realms you want on the list. Values in this list refer to calling SDP realms; this parameter has no default. To enter more than one realm in the list, list all items separated by a comma and enclose the entire entry in quotation marks:

   ORACLE(realm-group)# source-realm Private, Public

   To add a realm to the list, use the plus sign (+) in front of each new entry.

   ORACLE(realm-group)# source-realm +Private

   You can also remove single items in the list by using the minus sign (-) directly in front of the realm identifier.

   ORACLE(realm-group)# source-realm -Private

6. destination-realm—Enter the list of one or more global/SIP realms that you want to designate as destination realms for the purpose of blocking early media; this is the realm identifier value for the realms you want on the list. Values in this list refer to called SDP realms; this parameter has no default. To enter more than one realm in the list, list all items separated by a comma and enclose the entire entry in quotation marks:
7. ORACLE(realm-group)# source-realm Private, Public

   To add a realm to the list, use the plus sign (+) in front of each new entry.

   ORACLE(realm-group)# destination-realm +Private

   You can also remove single items in the list by using the minus sign (-) directly in front of the realm identifier.

   ORACLE(realm-group)# destination-realm -Private

   • none—Turns off the feature for this realm group by blocking early media

   • reverse—Allows early media to flow from called to caller
