During a new 4.1.3 call mgr install, 7961 phones hung during bootup. Had to remove the followimg cmds from the 3750 stacks to get them to boot:
Removed ip verify source from each interface
Removed ip arp inspection ?vlan info? from global config
Removed ip dhcp snooping ?vlan info? from global config
Since then, the phone loads have been upgraded to 8.0.4.sr1 and all seems well. I's like to tell customer that the new load fixed the problem, but I have yet to see anything about it in the release notes.
Has anyone run into this ?

I had a similar problem on 6509 switches with some 7.X.X phone load, but did not get a chance to upgrade the loads. Every new phone when connected to the network for the first time would get stuck in "Configuring IP".
Two workarounds:
1. "clear ip dhcp snooping binding"
2. Factory Reset the IP Phone

thanks.
Have you seen any Cisco notices on using/not using the dhcp snooping with ip phones?
