I have two DNs that will not work with BLFs on a 7965 ip phone. I'm not sure really what else to check. I have compared it with a working phone / DN and eveything would appear to match up.
What's 'everything' that you have checked?
If it's specific DNs that don't work I would first cheeck that the partition of the DN you want to monitor is in the SUBSCRIBE CSS of the 'watching' phone.
