My Call Manager Express 2801 is connected to a Catalyst on vlan 20; dhcp server is on vlan 10; if I plug the phone on the same vlan with 2801, it registers fine; if it's from a different vlan, the phone cannot register.
with "debug ccsip messages", I don't have any trace regarding to registration.
Using Ethereal, I capture the traffic on the port where 2801 is connected to. I see the registration request and response from 2801 says "401, unauthorized"
Please advise. Thanks.
