I have some cisco G7965 phone showing "IP Configuring" on the screen. Out Router has the dhcp scope configured to allocate IP's to IP Phones. I can see the IP arp mapping for the phone in question and also settings option on the phone shows that IP has allocated to the phone but for some reason phone can't register with CUCM where as other phones on the same VLAN has no issues what so ever.
I connected to phone using brower and have checked that phone has APP Load ID, Boot Load ID & version are identical to other phones. Hardware revision of the phone having issue is 10 where as other phone have Hardware revision of 9 apart from that everything else is identical. I have tried resetting the phone to factory defaults but made no difference.
Pls assist if you can..
Load Wireshark on your PC and on the phone's device configuration page - make sure that Span to PC Port is ENABLED. Set up Wireshark and then connect the phone to the standard port on the back of the phone. Then connect the phone to the network. You should see the boot sequence of the phone. Compare this to a good phone (one that is operating normally).
In contrast, you could connect your PC to another port on the switch and just span the port of the phone to the port your PC with Wireshark is connected to but you'll miss some of the info you get when you do a direct sniff from the phone.
If possible, turn off all the applications you can on your PC outside of the Wireshark to avoid any garbage info from your PC in the capture.
