The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Cisco IOS gateway registers all its POTS dial peers to the registrar when the registrar is configured on the Gateway. The introduction of trunk registration support, the registration of a single number would represent the SIP trunk. The SIP trunk registration can then be associated with multiple dial-peers for routing outbound calls. This registration represents all of the gateway end points for routing calls from or to the endpoints.
The Cisco IOS SIP gateway sends the REGISTER request to the configured registrar after resolving the outbound-proxy DNS name. Upon successful registration the Cisco IOS SIP gateway re-uses the Outbound Proxy IP address, port number, service-route response received for sending subsequent REGISTER/INVITE.
The existing enabling the outbound proxy CLI would be extended to turn on/off using the resolved IP address and port for a successful registration to all the subsequent outbound INVITE/REGISTER.

Use the following global or dia-peer configurations to associate a number with a dial-peer. When configured, the registration corresponding to this number is used for sending the OOD INVITE.
Use the following configuration to enable or disable authorization header support in REGISTER requests and associate the realm with the register. The configured private-id of the user is used for populating authorization header.
The following table provides release information about the feature or features described in this module.
