I was hoping someone can help me out as Bell Canada which is listed as an expert in all this has not been able to resolve the problem.
We have nortel iphones that do not work on DHCP at this one site. Here is the switchport config
Switch is a Cisco 3560
switchport trunk encapsulation dot1q
switchport trunk native vlan 10
switchport trunk allowed vlan 10,222
switchport mode trunk
switchport voice vlan 222
switchport priority extend cos 1
10 is the data vlan and 222 is the voice.
Here is the string for DHCP
option 128 = Nortel-i2004-A,XXX.XXX.XXX.XXX:4100,1,1;XXX.XXX.XXX.XXX:4100,1,1.
option 191 = VLAN-A:222.
When set to full DHCP the phones just get stuck and sit there responding back that they cannot find the DHCP server.
I have checked the scope and phone configuration against another location that works but for some reason we cannot get these phone sets to come up with DHCP.
Can anyone assist as I am all out of ideas
