Chapter 2 SIP Subscribers
SIP User Authentication
SIP User Authentication
The BTS 10200 can act as an authentication server. Authentication is enabled on the serving domain
through provisioning.
Whenever a SIP request is received from a SIP subscriber, the request is authenticated to ensure it is
indeed from an identified user. Authentication also enables request authorization, because users may be
authorized to perform only specific requests.
The following examples are the functional scenarios in which authentication is required:
1. When a SIP user registers a contact with the BTS 10200 Registrar using a REGISTER request.
2. When a SIP user initiates a call using an INVITE request.
3. When a SIP user sends any request in an ongoing call. Examples include
–
Re-negotiation of the call parameters using a re-INVITE
–
Terminating the call using a BYE
–
Initiating a call transfer using a REFER
4. When a SIP user sends a request outside a dialog. Example: OPTIONS.
The following tables affect authentication for SIP subscribers:
• AOR
• Serving Domain
• Auth-Realm
• User-Auth
See the Cisco BTS 10200 Softswitch CLI Database for more information about the tables.
