I have a home user using a Cisco 880 router runing 15.2(4)M4 code with a Mitel VoIP set.
The phone was working fine, but now is stuck in DHCP discovery.
Phone port is configured as follows:
interface FastEthernet2
description VOICE
switchport voice vlan 2
no ip address
end
DHCP debugs reveal this:
001157: *Mar 3 13:39:27.195 EST: DHCPD: client's VPN is .
001158: *Mar 3 13:39:27.195 EST: DHCPD: No option 125
001159: *Mar 3 13:39:27.195 EST: DHCPD: Sending notification of DISCOVER:
001160: *Mar 3 13:39:27.195 EST: DHCPD: htype 1 chaddr 0800.0f7b.3212
001161: *Mar 3 13:39:27.195 EST: DHCPD: remote id 020a00000a643c0902000001

001163: *Mar 3 13:39:27.195 EST: DHCPD: DHCPDISCOVER received from client 0108.000f.7b32.12 on interface Vlan1.
001164: *Mar 3 13:39:27.195 EST: DHCPD: Seeing if there is an internally specified pool class:

001167: *Mar 3 13:39:27.195 EST: DHCPD: circuit id 00000000
001168: *Mar 3 13:39:27.195 EST: DHCPD: Found previous server binding
001169: *Mar 3 13:39:27.195 EST: DHCPD: Sending DHCPOFFER to client 0108.000f.7b32.12 (10.200.60.10).
001170: *Mar 3 13:39:27.195 EST: DHCPD: no option 125
001171: *Mar 3 13:39:27.195 EST: DHCPD: broadcasting BOOTREPLY to client 0800.0f7b.3212.
The DHCP server seems to be providing the phone with an IP on the data vlan (VLAN 1), but not on VLAN 2. Not sure why I'm seeing this "no option 125" though.
I've tried stopping and restarting the DHCP service to no avail.
My DHCP server config looks like this:
!
no ip dhcp use vrf connected
ip dhcp excluded-address 10.200.60.9
ip dhcp excluded-address 10.200.64.113
!
ip dhcp pool sdm-pool1
import all
network 10.200.60.8 255.255.255.248
dns-server 10.200.207.24 10.200.207.21
default-router 10.200.60.9
netbios-name-server 10.200.207.45 10.200.207.43
netbios-node-type h-node
!
ip dhcp pool VoIP-pool
import all
network 10.200.64.112 255.255.255.248
dns-server 10.200.207.24 10.200.207.21
default-router 10.200.64.113
netbios-name-server 10.200.207.45 10.200.207.43
netbios-node-type h-node
option 128 ip 10.200.179.10 10.200.179.11
option 129 ip 10.200.179.10 10.200.179.11
option 133 hex 0000.0005
option 132 hex 0000.0002
option 130 hex 4d49.5445.4c20.4950.2050.484f.4e45
lease 30
!
If you have any thoughts on what I can try next, I'd love to hear it!!
Thanks in advance.

The DHCP logs are complaining about option 125. For Mitel you can use Option 43 or 125. Look over the link below, it may help you.

Thanks Yosh... I will take a look at this link.
My confusion is that we have never had to specify either of those options elsewhere in our VoIP network.
Cheers,
John
