Ip phone stuck in configuring IP

Hello

Have a question, My customer just plugged a phone to the Network and Its stuck in "configuring ip" we have auto-registration enabled, we have enough DNs available for this purpose, we issued a factory reset to the phone and we are still not able to register the phone correctly, it is a 7940 and we are running CCM 4.1(3) sr4d

Re: Ip phone stuck in configuring IP

Is DHCP configured with option 150 pointing to the TFTP server?

Do you have a voice (aux) vlan configured on the switch port the phone is connected to? If so, try connecting it to a switch port with the only one vlan configured that has access to the dhcp scope with the option 150 configured.

Some of the old 7940/7960 firmware had an issue with connecting correctly to switches that had an aux VLAN configured.

Re: Ip phone stuck in configuring IP

Dear, Simply add manul entry in DHCP with MAC Address of the phone and IP. you will then have to reset the phone. Hope that will work! otherwise please let me know do you have any vlans configured. If yes then please use 'Switchport voice vlan #' on that IP phone port. Please update the status after all

Re: Ip phone stuck in configuring IP

I wouldnt suggest you to play with router. You can easily configure DHCP on CCM for only 1 or few Phones. That will be easy and quick. Use this link to configure DHCP

http://www.windowsnetworking.com/articles_tutorials/w2kdhcpc.html - Then please also select 150 TFTP Server from 2nd last step. Finaly add a reservation in DHCP, after that add a phone in CCM manually. That should work.

Re: Ip phone stuck in configuring IP

I had to reconfigure the switch port.

re-add it to the voice vlan, that solved the issue

Re: Ip phone stuck in configuring IP

Configure DNCP, Add scope of one or two IPs, Conf router Ip in DHCP, then reset the phone hopefully it will be registered, if not then add it manually in CCM - it will be registered.
