<div>This may be an obvious question, but why is there a 2801 at each location? is it for SRST/911 purposes? Do all IP Phones have the same default gateway, or do they look to their respective 2801s to provide routing for them?</div>

The 2801 did have some sort of notice about a duplicate DHCP entry or some such thing....unfortunately, everything was happening so fast, and there is that need to JUST FIX IT,that there isn't a lot of time to write stuff down or gather relevant stats. <br>
<br>Looks like I will be doing further research!!<br><br>Todd<br><br>I think it might be time to set up my cisco gear so it logs relevant happenings to a syslogger on one of my linux/doze boxes.
