We have faced a problem, recently we have migrated to a CUCM9 we simply import our config to the CUCM (after solving its problem), after switching to new CUCM we had issues with some phones, hence we deleted the configuration security trust list and ITL file, after this the phones started to be registered but we lost some services like Voice mail (the button), Directories and phone designer services.
To check the problem I tested another phone which had not the same issue, I deleted the security trust list and bang the same problem appeared.
I do not understand what is the problem I tried
New Firmware and old Firmware.
I tried factory reset
Can you go to the web interface of a working and non working phone and compare their network configurations? I.E.
You stated you imported your configuration to CUCM. How did you export/import the config? Have you checked to confirm your Voicemail Profile and Voicemail Pilot are configured in CUCM 9? Have you also checked under Device > Device Settings > Phone Services to confirm all of your previous services moved over correctly?
I agree with Tony, but based on your post it sounds like you do not have any phones in your CUCM 9 environment that are working as expected to compare against.
Funny, the not working Phone has the url the correct one, but the working phone does not have that!!!!?????
You need to probe the issue by using Cisco RTMT. Take the appropriate traces and check the issue

Another issue is found, I can not go to the webpage of the problematic phones.
Yes I used Import and Export, I can dial my VM pilot and it is working fine, I also deleted one phone and tried to re-configure it from the base no changes.
I solved the problem, in the phone services, in the secure URL there was a "NULL" the rest was ok, I just remove this word, saved the setting and updated the subscribsion and voila problem is fixed.
and thank you for sharing your thoughts
