Size of msExchRecordedName Attribute

[admin_2]

We're looking to find the size of the msExchRecordedName attribute to understand what impact it will have on the size of our Active Directory database and the Global Catalog (which includes the attribute by default).<br><br>On CCO, at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/whitpapr/datadir.htm, all it says is "In general, the length of a recording for a voice name will be approximately 2 seconds. The size depends on the codec, and on the version of Cisco Unity used to make the recording. The size of recorded voice names in version 3.1(2) (and later) of Cisco Unity is smaller than in previous versions."<br><br><br>

According to our in-house AD guru:

=================

The recordedname will end up being the size of the wave file x 1.3.

All other Unity attributes for the user object are roughly 500-600 bytes. This means, if the average recorded name length is 2 seconds and G.711 is used, the Unity subscriber attributes including recorded name will be about +/- 21 KB. For G.729a, it will be about +/- 2.9 KB or little larger. To get the total size of a given user object in AD, it is necessary for the customer to know what the average size of their user is now, and then they can reasonably add the formula above to determine the added increase for each Unity subscriber.
