[cisco-voip] max devices controlled by a ccm user

I can't recall exactly what it was, but I'm pretty sure there was a new Unity feature that required a phone be assigned to a particular CTI user be assigned all the phones it was going to control. I believe it was for the message interruption, so if someone was leaving a message on your VM your phone would get a new softkey to intercept that call or listen to it live. If you wanted this feature on all of your phones, that user had to be assigned all these MAC addresses!

  that took a while.

  CM4.x SRND:
  http://www.cisco.com/go/srnd

  "NoteThe list of devices associated with a user is stored in the directory as a multi-valued attribute. If you are using the embedded Cisco Unified CallManager 4.x directory (known as DC Directory), the maximum number of devices that can be associated with a user is 2,000 (or 2,500 if all subscribers in the cluster are dual-CPU servers). However, Microsoft Active Directory limits the number of values that can be stored in a multi-valued attribute. The total size of the record should never exceed 7,000 bytes, which allows for approximately 850 attribute value"

    Are these limits published somewhere?  I guess that is a stupid question.for AD it would be on www.microsoft.com.

    What LDAP are you using for CM?  DCD (native) / Active Directory / Netscape / ...

    Usually this is limited by the field size in the associated ldap storage base.

    I have an IP Phone Service that requires that the CTI user associated with the service has each phone that runs the service as a controlled device.  



    I went to add the 1584th device to it, and I got an "Error: -11" with no description.  



    That seems like a strange number to finally error out on if there is a limit to the number of devices controlled by one user. 



    I am running CCM 4.1(3)sr5b.



    Thanks,
