We have a centralized CallManager Cluster (4.1.3 upgrading to 5.1.2 soon)
Is it technically possible (albeit not likely supported )to have the phone load hosted by the TFTP services of an SRST router. The phone config files would still reside on the servers. The goal is simply allow the phone to receive it?s upgrade from a distributed (local to the phone) source.
My understanding of the TFTP process is that when the phone boots it looks to the configured primary TFTP source for it?s configuration file and if it is not found will go to the secondary.
One con of this is that with only two tftp servers there would be no redundant (tertiary) tftp source for the phone config files.
