IP Phone not pulling DHCP FW2.83

[ppenning]

Hello All,
I have a strange on here... 99% of my IP phones at one location are working fine. However, I have 2 phones that were working fine but then got unplugged for a short period of time. Now they will not pull a DHCP address. The PC's which are plugged into them are pulling an IP address just fine (Different Subnets and Vlans but same DHCP Server).

The phone just comes up and gets stuck reading DHCP... Press * to program.

Any thoughts?
Thanks in advance!
Perry

Did you try to clear the phone ?

Press the * and then Keep pressing # untill the phone says enter command

Then Press hold and clear and #

See what happens then

Thanks... Press Hold, Clear, and #? I don't have a "Clear" button on the phone. I have always done Mute R-E-S-E-T-# What you are telling me is new. Sounds good though... What do you mean by clear?
Thanks,
Perry

Check the dhcp server for the mac adresses of those phones and remove them out of the lease list (or how it is called)
Then try again

We're on the same track... I am trying to get with our Server group now to do this... My bet is that it's the DHCP Server...
Thanks!

We had a similar issue and it ended up being there was a maximum amount of DHCP addresses allowed in the server. While we had (in our case) a pc unplugged something else was connected and took the last available address. After the max limit was increased we were ok.

I have also seen this problem resolved by doing one of these:
1. Plug the phone into a different LAN port
2. shut the LAN port, then no shut (cisco centric)
