152 Polycom, Inc.
Enterprise Conference Room ID Generation 
Directory attribute  The name of the Active Directory attribute from which 
the Polycom DMA system should derive conference 
room IDs (virtual meeting room numbers). Generally, 
organizations use a phone number field for this. 
The attribute must be in the Active Directory schema 
and preferably should be replicated across the 
enterprise via the Global Catalog server mechanism. 
But if the attribute isn’t in the Global Catalog, the system 
queries each domain controller for the data. 
Leave this field blank if you don’t want the system to 
create conference rooms for the enterprise users. 
Characters to remove  Characters that might need to be stripped from a phone 
number field’s value to ensure a numeric conference 
room ID. 
The default string includes \t, which represents the tab 
character. Use \\ to remove backslash characters. 
If generating alphanumeric conference room IDs, 
remove the following: 
()&%#@|"':;, 
Single spaces in the source field are preserved, but 
multiple consecutive spaces are concatenated to one 
space. 
Maximum characters 
used 
Desired length of conference room IDs. The Polycom 
DMA system strips excess characters from the 
beginning, not the end. If you specify 7, the room IDs will 
contain the last 7 valid characters from the Active 
Directory attribute being used. 
Enterprise Chairperson and Conference Passcode Generation 
Chairperson directory 
attribute 
The name of the Active Directory attribute that contains 
the chairperson passcodes. In choosing an attribute, 
remember that passcodes must be numeric. 
The attribute must be in the Active Directory schema 
and preferably should be replicated across the 
enterprise via the Global Catalog server mechanism. 
But if the attribute isn’t in the Global Catalog, the system 
queries each domain controller for the data. 
Leave this field blank if you don’t want the system to 
create chairperson passcodes for the enterprise users. 
Maximum characters 
used 
Desired length of chairperson passcodes. The Polycom 
DMA system strips excess characters from the
