I've an issue with a 9951 phone with VPN enabled. Using certificate and auto-detect network, it works perfectly for everybody, except at one location where the phone is not getting any IP from DHCP...
In admin settings -> Ethernet statistics we can see NOT VALID ENUM
If we plug a laptop on the same ethernet cable, we get an IP address, we don't ping the CUCM TFTP and we an reach the https://ip_of_asa/phonevpn so normally the VPN should start.
The same phone plugged at another location works without any issue.
9951 has the lastest sip9951.9-3-4-24 fw, ASA is almost up-to-date, CUCM is 8.6.2
What could be the reason for not getting an IP specifically for a phone with error "NOT VALID ENUM" ?
