96xx phone takes 5 hours to boot up

[westom]

during a recent office move, I have an issue where any 9608 phone that is unplugged, takes several hours to boot up again. I have checked the network and is as follows:

phone boots into customer data vlan234
gets string from DHCP server: L2QVLAN=160

the phone then sits there with dhcp=5 vlan=160 until it finally sorts itself out and boots up.

the voice vlan has the 242 string on Cisco switch
= option 242 ascii MCIPADD=*.*.*.*,HTTPSRVR=*.*.*.*,HTTPDIR=/tftpboot,L2QVLAN=160


all phones are working before reboot, and do finally come back, but I need to move lots of phones and dont know whats changes on the network/dhcp may have caused this, any ideas, things to check please?

Upgarde the phone to latest firmware and check VLAN settings and DHCP scope.
Either the phone is not getting the right DHCP scope or is trying to reach a wrong DHCP
