The BTS 10200 validates the hostname of the ReqUri of every incoming SIP request against the list of names provisioned in the Serving-Domain-Name table. The BTS 10200 hostname used by devices (in the ReqUri), when they send requests to the BTS 10200, should be provisioned in the Serving-Domain-Name table of that BTS 10200. If a name is not provisioned (and therefore not found) in the Serving-Domain-Name table, the BTS 10200 rejects the SIP request with a “404 Not Found ReqUri Serving Domain” response.

The BTS 10200 authenticates IP phones by using the MD5 digest defined in RFCs 3261 and 2617. The BTS 10200 verifies a user’s credentials on each SIP request from the user. For more information, see the User Authorization table in the Cisco BTS 10200 Softswitch CLI Database.

SIP Subscriber Calls

SIP subscribers must present valid credentials on a SIP INVITE message in order to place calls.

The system allows SIP subscribers to call other SIP subscribers or SIP trunks connected to the BTS 10200. The provisioned dial plan determines whom a subscriber can call. A SIP subscriber can receive a call as long as the subscription’s registration is current, or a static registration has been provisioned.
