Avaya IP Phones constantly rebooting (DHCP ACK)

Avaya IP Phones constantly rebooting (DHCP ACK)

(OP)
Hey all,

Thought I might try posting in this forum given it relates to the ERS3510GT-PWR+

My IP Phones (SIP & H.323) are constantly rebooting daily. I know typically the above can be a result of having two active DHCP servers. I'm very new to networking (I'm more telco) but spent a lot of time researching when I was setting up my Avaya ERS3510GT-PWR+ for my home network and established VLANS for Data & Voice. I'm running IP Office R11.0.4.5 and have a mix of J169, J179 and a 9641GS on the system.

Background of VLANS:

VLAN 1 (Data) DHCP Range: 192.168.0.1XX - 192.168.0.199 (VLAN 1 IP Address: 192.168.0.11)- All customised options set
VLAN 10 (Voice) DHCP Range: 192.168.10.1XX - 192.168.10.199 (VLAN 10 IP Address: 192.168.10.1)- All customised options set

DHCP Relay: 192.168.10.1 to 192.168.0.0 <--- not actually sure I need this because the phones automatically go over to VLAN 10 due to my LLDP MED settings, however I did originally need this when the IPO was on VLAN 1. I've since moved the IPO to VLAN 10 and given it the IP Address 192.168.10.10 - Is this causing the issue and should I remove the settings completely?

Router/Modem Interface/Subnet 1: 192.168.0.1/ 255.255.255.0
Router/Modem Interface/Subnet 2: 192.168.10.2/ 255.255.255.0
DHCP disabled on the Router/Internet.

IP Office:
LAN 1 IP Address: 192.168.10.10
LAN 2: Not in use.

Route in IPO: 0.0.0.0/ 0.0.0.0/ 192.168.10.2

IP Office port's default VLAN is the Voice VLAN 10.

The IP Office DHCP server is disabled.

I was also having a strange issue I raised on another post where sometimes the Passthrough port on the back of the J100 series SIP phones was giving out a strange DHCP Address, again which could be caused by too many DHCP servers.

I just feel like there is something I'm overlooking (due to my experience no doubt on the Networking side). Any suggestions would be greatly appreciated so these phones stop rebooting on their own!

Thanks for your help as always.

Thanks, Tim
