IP Phones getting IP address outside of scope.
Posted on 2006-07-03
We have 65 Shoretel IP Phones and they are all pulling addresses outside of DHCP scope which means they do not update the CFG files automatically and the date and time is incorrect. We have our scope setup from 16.0 to 20.255 and exclude 16.0 to 16.255 for network appliances, 17.0 to 17.255 for servers, and 20.0 to 20.255 because we aren't using this range. We are using 18.0 - 19.255 for computers, phones, and printers.
The problem is everytime we clear the IP address from the IP Phones they continually get a 20.x address which is in our exclusions range which means they do not get a proper lease and there for will not update the date and time correctly.
We have rebooted the domain controller (DHCP Server), shoretel server, phone switches, and the phones themselves. We have contacted our vendor and they can't figure out if the problem lies within the network or the phone system.
I'm hoping one of you fine experts out there might be smart enough to atleast point us in the right direction.
Thank you in Advance
