I am mystified with my configuration. I have 7942 ip phone it is supported by my 2921 router with os version 15.2(M4). I was able to configured it successfully last week and it is working well. Since i dont have a full license for unified communication, i decided to temporarily disable uck9 EvalRightToUse license.
just this morning i re-enabled uck9 package, and reconfigured the said ip phone. phone firmware is installed and ok, tftp-server flash:xxx files are present, loads file SCCP42.9-1-1SR1S.loads is loaded, i have re-created cnf-files. i have also checked configurations, sh telephony-service tftp bindings and it appears ok.
But despite all of these, the ip phone is stuck on REGISTERING...
Im frustrated since i have successfully configured it before, and now i've spent almost a day fixing it over and over again
Your licenses look fine. Can you check the debugs for debug ephone register, debug tftp events ? Reset the phone and collect these debugs. Let's see what's happening when the phone tries to register with the CME
