Dear Team,

I have more than 1000 ip phone in my organisation and ip for ip phone is getting DHCP server configured in our  core switches (cisco 6500).

Now we are planning to remove the DHCP server form core switch and configure in a separate server.

To receive ip from the newly created dhcp server IP phones need to restart.

If I restart manually one by one there is possibility for getting ip conflict.

So I am thinking about to restrt all the ip phones  in same time  with restart schedule.

Is there any option in CUCM  to schedule a restart for all the phones ? or any body can suggest a fruitful solution for this situation.

You can specify BAT phone update jobs with restart at specific time.

Hi Rafi,

My friend Chris is most correct here (+5 for yet another great tip Chris!)

BAT is the way to go here Rafi;
