[cisco-voip] Call Diagnostic Records - CMR

[Ryan Ratliff]

You are correct that each CDR will get a corresponding CMR. In fact  
you will get multiple as you have one CMR for each party that  
supports CMRs involved in the call.  They are also generated for each  
RTP session so if RTP is renegotiated for a call going on hold, etc  
can result in many CMRs per call.

Just trying to be semi cautious before turning it on. Based on the  
explanation of the field it looks like it could be problematic if it  
was buggy in regards to disk/partition space. I did not see any  
issues in the Bug Toolkit so I thought I would ask here. Right of the  
bat I assume this will double the number of the CDR records being  
sent out. For reference here is the detail on the field:

Call Diagnostics Enabled: <mime-attachment.gif> 	
This parameter determines whether call management records (CMR), also  
called diagnostic records, are generated. Valid values specify  
Disabled (do not generate CMRs), Enabled Only When CDR Enabled Flag  
is True (generate CMRs only when the CDR Enabled Flag service  
parameter is set to True), or Enabled Regardless of CDR Enabled Flag  
(generate CMRs without regard to the setting in the CDR Enabled Flag  
service parameter). Generating CMRs without corresponding CDRs can  
cause uncontrolled disk space consumption. Cisco Systems recommends  
that you always enable CDRs when CMRs are enabled. If you choose  
Enabled Only When CDR Enabled Flag is True and the CDR Enabled Flag  
service parameter is set to False, no CMRs will be generated.

I would of course use the "Enabled Only When CDR Enabled Flag is  
True" option.

Can you be more specific? What are you seeing that you think is  
related to turning on CMRs?

Sorry for the hijack, lets try this again....
Has any one had any issues after turning on Call Diagnostic Records -  
CMR in CallManager 6.1.1?
Thanks!
