Can't get 8831 to register with CME

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: 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.

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

Re: Can't get 8831 to register with CME

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.

Re: Can't get 8831 to register with CME

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.
