I've got CME on a 2821 Integrated Services Router, and a bunch of 7921G wireless phones. They will register with the 1.2.1 firmware that was originally loaded, but I'm trying to update to 1.3.3 and also to add some custom ringtones, and they are generating some errors when I reset them:
-04:49:34p CFG File Not Found
-04:49:34p XMLDefault.cnf.xml: TFTP Error
-04:49:34p SEPMACADDRESS.cnf.xml: TFTP Error
The files for the firmware were uploaded to the router's FLASH: (along with my ringtone files).
I ran the tftp-server commands via telnet.
I ran the "load 7921 CP7921G-1.3.3" from telephony-service. I also ran the "no create cnf-files" and then ran "create cnf-files" commands based on another thread I found here.
Then I restarted a few of the phones and they all trigger the same result.
I know I'm missing something (and it's probably simple), but any ideas on how to proceed?
If you have a cisco AP, recommend you use a separated SSID/VLAN for voice.
This way, you will not depend by an external DHCP server, and all your phones will be in the same VLAN.
