TFTP server failover

[believ1]

Gentlemen, CCM is a nice way to implement a fully redundant Call Processing architecture. Publisher, Subscriber etc.

However, suppose my Publisher acts as TFTP-server.

In DHCP option 150 I specified the ip-address of the publisher. If this publisher is out of service and a new (already registered phones continue working with 'cached' data?) phone comes online it cannot register or contact its tftp-server. Is there any means to overcome this?

Thanks in advance

we are about to implement a 'warm' publisher, the same as what u are looking to do. As far as i know cisco do not document something like this? any info would be good
