Can't get 8831 to register with CME

[Clifford McGlamry]

Customer has 2921 running CME on c2900-universalk9-mz.SPA.157-3.M4b.bin

Attempting to bring up CME.  Phone refuses to register.  Have cleared the ITL file, reset to factory defaults, but it simply refuses.  Debugging the TFTP and SIP traces, the only thing I really see is where it does this:

Jul 25 18:31:38.009: TFTP: Looking for SEPAC44F21AA1FF.cnf.xml.sgn
Jul 25 18:31:38.013: TFTP: Sending error 1 No such file
Jul 25 18:31:41.821: TFTP: Server request for port 57871, socket_id 0x400CA218 for process 170

Jul 25 18:31:41.821: TFTP: Looking for XMLDefault.cnf.xml.sgn
Jul 25 18:31:41.821: TFTP: Sending error 1 No such file

Nothing shows up in the CCSIP traces.

Config looks like this:

I'm banging my head on the wall.  What am I missing?  The phone takes the firmware, but won't register.

Hi there

Try 

conf t

telephony-service

create cnf

and do a restart of CME

Hope this Helps

So, the 8831 is a SIP phone.  I was under the impression that create cnf created the configuration files for SCCP phones, and that to do the equivalent for SIP phones you had to do:

voice register global

create profiile

Do you also have to do create cnf under the telephony-service?

And to restart CME, we talking reboot the router, or just restarting the sip call service? 

I haven't worked with CME in a while, so this is all a bit rusty.

I see under voice register global that you have "authenticate register", but I don't see the other parts (realm, username/password, etc.) for device authentication. So try removing the "authenticate register" command from voice register global, do the "create profile", and see what happens.

While the device is attempting to register, run a "debug voice register events" along with the TFTP debug.
