I've been having issues with 7911s at several installs now. Basically what happens is that I plug in all the phones, all the 41s, 61s, etc all register real quick, but the 7911s sit there FOREVER configuring IP. I know that they pull an IP from DHCP but they take their sweet time trying to do an upgrade. I've had this problem ONLY with the 11s and on both CME and Call Manager 5.1. Anyone else see something like this? Is there a fix? Right now I just wait for them to come up (some come up after 20+minutes) or sometimes a forced reset via the keypad helps.
