ISA570W DHCP Lease Time

Hi,

I am trying to get our 50 cisco phones not to request an IP address twice a day even though the DHCP settings are set to 1d and 12h.  I have been hunting around the web to figure out how to extend the DHCP lease time to be more than 1d 24h 59m, on other cisco equipment you can set an infinite option.

Hope somebody can help.

Gareth

Hi Gareth,

This limitation is by design as normally you would not necessarily want to have lease time too long.

Not sure how good would be for you to set static IP but for troubleshooting phones issue perhaps needed.
