Hi,
Can you try the following steps:
Add a user in CCM with user ID of the DN , for example 1000
-add the sip profile or use default
-add a SIP Phone security profile (non-secure) and enable digest
authentication
-add the 3rd party SIP phone manually (Device/Add)
(i believe you need to change this Enterprise parameter to make it work as
SIP for auto registration: "Auto Registration Phone Protocol")
-associate the user you created to this phone
On the phone itself:
-you need the SIP proxy address which is your CCM IP address: example :
10.1.1.1: 5060
-add that user ID you created in CM 1000
** note **
"Enabling Digest Authentication for Third-Party SIP Phones
To enable digest authentication for third-party SIP phones, the
administrator must create a Phone Security Profile. (See Phone Security
Profile Configuration in the Cisco Unified CallManager Administration
Guide.) On the Phone Security Profile Configuration window, check the Enable
Digest Authentication check box. After the security profile is configured,
the administrator must assign that security profile to the SIP phone by
using the Phone Configuration window. If this check box is not checked,
Cisco Unified CallManager will use digest authentication for purposes of
identifying the phone by the end user ID, and it will not verify the digest
password. If the check box is checked, Cisco Unified CallManager will verify
the password"
