Configure Surrogate Registration

You configure this surrogate registration SPL feature on the realm-config or sip-interface facing the trunk. Configure the random contact exclusion on the ingress realm-config for KDDI environments only.

1. Access the sip-interface configuration element.

   ORACLE# configure terminal
   ORACLE(configure)# session-router
   ORACLE(session-router)# sip-interface
   ORACLE(sip-interface)# 
   

2. Select the sip-interface object to edit.

   ORACLE(sip-interface)# select
   <RealmID>:
   1: realm01 172.172.30.31:5060
   
   selection: 1
   ORACLE(sip-interface)#

3. If using this surrogate registration SPL configuration for a trunk, configure this option on the sip-interface facing the NTT or KDDI trunk.

   ORACLE(sip-interface)# spl-options +Control-Surr-Reg

4. If using this surrogate registration SPL configuration for a trunk, Configure this option on the sip-interface facing the CUCM realm.

   ORACLE(sip-interface)# spl-options +dyn-contact-start

5. If using this surrogate registration SPL configuration for a trunk, configure this option on the sip-interface facing the NTT or KDDI trunk.

   ORACLE(sip-interface)# spl-options +dyn-contact-method=randomseed

6. Type done and save your work.

Note:

The next steps, applicable to the contact validation exclusion features, applies only for KDDI deployments.

7. If excluding the contact validation component of the SPL surrogate registration function for a KDDI trunk, move to the realm-config configuration prompt.
8. Access the realm-config configuration element.

   ORACLE# configure terminal
   ORACLE(configure)# media-manager
   ORACLE(media-manager)# realm-config
   ORACLE(realm-config)# 

9. Identify the applicable ingress realm, on which you set this SPL option.
10. Select the realm-config object to edit.

    ORACLE(realm-config)# select
    identifier:
    1: realm01 left-left:0 0.0.0.0
    
    selection: 1
    ORACLE(realm-config)#

12. If using this surrogate registration SPL configuration for a trunk, configure this option on the realm-config facing the CUCM realm.

    ORACLE(sip-interface)# spl-options +dyn-contact-start

13. If using this surrogate registration SPL configuration for a trunk, configure this option on the realm-config facing the KDDI trunk.

    ORACLE(sip-interface)# spl-options +dyn-contact-method=randomseed

14. If excluding the contact validation component of the SPL surrogate registration function for a KDDI trunk, type spl-options +dial-inservice-validation to apply this feature on the applicable ingress realm.

    ORACLE(realm-config)# spl-options +dial-inservice-validation
