E-CSCF Configuration

This procedure assumes that the Oracle Communications Unified Session Manager is configured to communicate with a CLF. In addition, this procedure assumes an the Oracle Communications Unified Session Manager is configured and loaded with an appropriate LRT for E-CSCF Use.

To configure an NMC for E-CSCF use (baseline parameters are not mentioned):

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal

2. Type session-router and press Enter to access the signaling-related configurations.

   ORACLE(configure)# session-router

3. Type net-management-control and press Enter.

   ORACLE(session-router)# net-management-control

4. name—Enter the name of this network management control rule; this value uniquely identifies the control rule. There is no default for this parameter.
5. state—Enable or disable this network management control rule. The default value is enabled. The valid values are:

   • enabled | disabled

6. type—Set this parameter to priority so that the Oracle Communications Unified Session Manager will flag incoming calls with a matching destination identifier as a priority calls.
7. treatment—Set this parameter to divert.
8. next-hop—Leave this parameter blank so that the call’s processing will go directly to local policy.
9. destination-identifier—Enter the service URN that endpoints in your network include in their request URIs to identify themselves as emergency calls.
10. Save your configuration.

    To configure local policy for E-CSCF use (baseline parameters are not mentioned):

11. In Superuser mode, type configure terminal and press Enter.

    ORACLE# configure terminal
    ORACLE(configure)#

12. Type session-router and press Enter.

    ORACLE(configure)# session-router
    ORACLE(session-router)#

13. Type local-policy and press Enter. If you are adding this feature to a pre-existing local policy configuration, you will need to select and edit your local policy.

    ORACLE(session-router)# local-policy
    ORACLE(local-policy)#

14. to-address—Set this parameter to the lookup key for matching emergency calls. You can now use a service URN as lookup key criteria.
15. Save your configuration.

    To configure policy attributes for E-CSCF use (baseline parameters are not mentioned):

16. Type policy-attributes and press Enter. If you are adding this feature to a pre-existing local policy configuration, you will need to select and edit your local policy.

    ORACLE(local-policy))# policy-attributes
    ORACLE(policy-attributes)#

17. next-hop—Set this parameter to lrt: name-of-elrt-file.gz for this policy attribute to lookup routes in the named lrt file.
18. eloc-str-lkup—Set this parameter to enabled for the Oracle Communications Unified Session Manager to parse the emergency location string, as received in a CLF Line Identifyier AVP, for emergency LRT lookup.
19. eloc-str-match—Set this parameter to the attribute name found in the location string whose value will be used as a lookup key in the LRT named in the next-hop parameter. Common values include “loc” or noc.
20. Save and activate your configuration.
