Set up SIP Phone Digest Authentication
The following procedure provides the tasks used to configure digest authentication for phones that are running SIP.
Configure the security profiles for phones that are running SIP; make sure that you check the Enable Digest Authentication check box.
Apply a security profile to the phone that is running SIP.
If you want to update the default setting, configure service parameters that are related to digest authentication; for example, configure the SIP Station Realm service parameter.
Configure the digest credentials in the End User Configuration window.
Choose the Digest User in the Phone Configuration window.
Choosing a digest user for these phones that are running SIP ensures that the digest credentials get included in the phone configuration file.
On Cisco Unified IP Phones 7942 or 7962 (SIP only), enter the digest credentials that you configured in the End User Configuration window.
For information on how to enter the authentication name and password on the phone, refer to the Cisco Unified IP Phone Administrator Guide for your phone.
