[cisco-voip] Phones not Registering on CME

[Nowacki Marcin]

Try factory reset, If phones will still stuck, It must be DHCP considerations or maybe you are missing vlan on second layer ( check vlan database ).

It sounds to me like your phones are in the wrong vlan, thus getting the wrong IP address and quite possible the wrong or no option 150 information?

If your end users go into the phone settings what Voice/Data vlan is it claiming to have?  Could it be pointing to something other than the CME you think its hitting?   Find out from the phone itself which CM / tftp / dhcp server its communicating with.

If the phone is stuck in configuring IP I'd question what the phone is learning from DHCP, which may be controlled by the vlan and any respective helper addresses.

I get a call from some users at a remote site who are finally connecting the last series of phones to the CME I set up months ago.  They said that only 1 of the 4 phones are working.

The 3 phones (all 7962s) are stuck in the "Configuring IP" state and will not do anything else.  I've double-checked my configuration and I have correctly provisioned all the phones & their MAC addresses in the configuration.

Digging deeper, it seems that the 3 phones that are not getting the correct IP address.  I set up the DHCP pool to be 10.10.10.X/24.  All the functioning phones are obtaining the proper IP addresses but the 3 non-functioning phones are getting a 10.10.3.xxx address (so the user tells me).  Doing a show cdp neighbor details command on the ports show that there are no IP addresses associated with those ports.  Furthermore, the Version of phone shows up as "79XX_default_load" rather than "SCCP42.8-3-2S" on all the other functioning phones.  The port configurations are identical on all ports.

Do you guys have any ideas?  I'm using SCCP for my phone system.  My CME version is 7.1.
