I have been noticing a lot of SUBSCRIBE messages in my logs and have cleaned up 
a lot by making changes to client configurations.  

However, I notice a residual set of SUBSCRIBEs that are sent by the sipxRLS 
service to each extension that is enabled for voicemail (even ones with no 
phone attached).

I traced one that went to one of my ATA devices, and it came back "501 not 
implemented".  I can share a full trace if needed, but here is the contents of 
the initial message from sipxRLS:

I wonder what purpose these serve and if they are necessary?  

Thanks,

Jeff
