Subscription-Id-Type

The Oracle Communications Session Border Controller can send a Subscription-Id-Types AVP to an external policy server:

Value	Name	Description
0	END_USER_E164	Identifier is in international E.164 format (e.g., MSISDN), according to the ITU-T E.164 numbering plan.
1	END_USER_IMSI	Identifier is in international IMSI format, according to ITU-T E.212 numbering plan as defined in [E212] and [CE212].
2	END_USER_SIP_URI	Identifier is in the form of a SIP/SIPS URI.

To send the Subscription-ID-Types AVP in an AAR, you must add the include-sub-info option in the external policy server configuration element. If this option is enabled, and you do not configure a subscription-id-type in the realm-config, the contact header of the received message is sent in the AAR.

You can also set the Subscription-ID-Type on a per-realm basis by configuring the parameter subscription-id-type in the realm-config element to determine the value of the Subscription ID in the AAR.

The default value for subscription-id-type is END_USER_NONE. If the value of subscription-id-type is set to END_USER_NONE, and the external policy server option is enabled to send the Subscription ID AVP, then the Oracle Communications Session Border Controller relies on the contact header of the received message.

If the value for subscription-id-type is set to one format, such as END_USER_IMSI, but the contact header is set to another format, such as END_USER_SIP_URI, the value of subscription-id-type is used to send in the AAR message.
