Default DHCP Ack error

Intermittent DHCP ack error with 9611 phone. Some posts are saying different options than the one I have configured. This has been working for 2 years with no issues until recently. Below is my config. Any thoughts??

ip dhcp pool Avaya
network 10.21.0.0 255.255.248.0
default-router 10.21.0.1
dns-server 10.1.1.51 10.1.1.29
domain-name xxxxxx.com
option 242 ascii L2Q=1,L2QVLAN=20,MCIPADD=10.20.9.100,MCPORT=1719,H TTPSRVR=10.20.9.148"
lease infinite

Verify there isn't more than one DHCP server responding to the phones. Also, it looks like your DHCP server is in the data VLAN? Make sure the switch port it's connected to isn't tagging the voice VLAN.

That should be the only DHCP server responding on that VLAN. Also--here is a typical switch port config

interface GigabitEthernet1/0/2
switchport access vlan 5
switchport mode access
switchport voice vlan 20
srr-queue bandwidth share 10 10 60 20
queue-set 2
priority-queue out
mls qos trust cos
auto qos voip trust
