Parse error on a 1230 IP phone

[tausloos]

Try to set up an IP phone on our DHCP vlan and I am getting a DHCP parse error. I am not sure of my programming on the phone. Would anyone have a generic set of program instructions that might walk me through this? Any help is greatly appreciated.

Thanks much,

We got that before too - it could be phone firmware related. But if I remember correctly we had to put them back to factory default.

Also double-check your DHCP strings (post them if you aren't sure) Could be as simple as a , instead of a ;

Are you using partial or full DHCP? With full, you have to have the DHCP server provide, using options, all the information such as S1 address, ports, and IP address information. With partial, you provide the S1 IP and port information and the DHCP server supplies the IP, mask, and gateway. You also need to program the vlan information in either scenario unless you're using LLDP on your network.

Is the DHCP server OS Windows2003 or Windows2008? I believe we had problems similar when the DHCP server was 2008. We are on '03 now but are trying to work through problem when using Windows2008 as the OS for the DHCP server. May not even be related.

Check your DHCP server the strings in options 128 and/or 224, along with option 191 (VLAN). Usually a parse error means your string isn't properly formatted.

Assigning a few test phones static IP addresses will help troubleshoot.

We had a customer lose their DHCP server due to their poor IT maintenance practices... we had to come in and manually program each phone with static IP addresses, S1, S2, etc..., which was an expensive lesson for them.

Latest firmware has ability to use other mechanisms (TFTP, FTP, HTTP) to provide configuration information to 11xx/12xx/2007 phones. This reduces the need to use DHCP strings.

Your string should look something like this (notice lldp is no)also take special note of the , at the start and ; between the settings:

Nortel-i2004-B,s1ip=10.10.10.10;p1=4100;a1=1;r1=5;s2ip=10.10.10.11;p2=4100;a2=1;r2=5;xip=0.0.0.0;xp=5000;xa=g;unid=MY_CO;menulock=u;vq=y;vcp=3;vmp=4;vlanf=y;pc=y;pcs=a;pcd=a;dq=y;dv=y;dvip=60;dp=5;pcuntag=n;lldp=n;pk1=;pk2=;cachedip=n;igarp=n;srtp=n;dim=y;bt=n;
