Hi Anthony,

At the moment this looks like it would be a feature request.  The prudent path forward is to open a TAC case for more formal investigation.  Then if it turns into feature request we can engage your account team.

Regards,
Wes

Thanks for the reply Wes.
 
Is Cisco somehow intentionally ignoring this feature pairing for the time being?  I find it odd that it's not listed as a limitation or restriction of centralized TFTP.

auto reg isn't going to work so well with centralized TFTP.

centralized TFTP very basically does this:
If file is not found locally then request it from the defined peer TFTP servers

In this case autoreg uses information in xmldefault.cnf.xml which will always be found on the centralized server. *if* it works your phones would all register in the cluster that performs as the centralized TFTP server.

Cisco VoIP Group,
 
I am reading the following section of the UC SRND:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/8x/netstruc.html#Centralized_TFTP_Services
 
And I am wondering how phone auto registration is affected by the Centralized TFTP model?  Or if it's even supported?  If so, what are the limitations?
 
I don't see this referenced in the SRND, and would be open to reading any supporting documentation I am pointed to.
 
Thank you,

Anthony
