customer has ccm bus edition, 6.1.2. have a local 2851 router/gateway running srst. ccm is dhcp server for phones. I've tested the srst function, but today the server malfunctioned and phones did not go into srst mode. instead the phone display said " ip address released".
the server remained connected but could not be pinged.
any idea why phones didn't go into srst?
I arrived on site after the server motherbd was replaced and when server was shutdown, phones went into srst mode.
Further to the good information by Chris, another reason to be aware of is that there maybe still situations where the IP Phones were still able to communicate with the primary CallManager.
In this situation the IP Phones would still be receiving keepalives from the Publisher, and only in the event that it missed these keepalives would the IP phone re-register to the gateway.
Essentially the server did not experience a complete failure, and as soon as the server was shutdown the IP Phone would longer receive the keepalives and after approx. 90 seconds the phone would re-register.
