Cisco 7941G IP Phone: Registration Rejected: Error Mismatch

I have seen this sort of thing before,  but just never taken the time to write about it.  I have recently had a Cisco 7941G IP phone that I needed to add for my own remote office setup.  I went into CUCM 9.1(2) and added the phone in and gave myself the correct DN.  All looks good, except that when I go to boot the phone up, I get the following message:

Im not real sure why I get this, and according to the phone profile, its the correct type.  However, if I delete my phone out and add it back as a 7941 (not the G-GE), it works correctly.  To me, that just seems odd, since the first time I did correctly select the right type of phone.


  1. you have to add manually the device and select the appropriate version /model of the phone.

    i got the same issue. i think its the device pool security or the model you choose is not correct.

    1. Nope, everything was configured correctly. Good try though.

  2. delete the phone and add them again but this time change the type to SCCP 7941

  3. Fixed this by deleting the End User under User Management. Was trying to move the phone to a different Device Pool.
