Can you try configuring exactly as the config I pasted in my previous comment earlier and then check.

Also if possible try connecting the 7821 phone to one of the port wherein you already have a working phone

Deepak,

existing phones are not registering (example: 7911, 7945), please help

So you are saying none of the phones are registering. Is that correct??

By any chance you have the show run before the IOS upgrade. If yes, then match with the current config to see if any command had gone missing. Did you try relaoding the router to see if that helps.

Regards

Deepak

Finally I got my existing phones back up and running, and also the new 7821s.

You can go with IOS version 15.4.3M4 which is the current stable one.

Hello Rajan,

Kindly give me complete code for this IOS, so that I could download it.

And I hope this IOS version does not impact CUE and other running-configuration, right??

This IOS actually upgrades your CME version to 10.5. I dont think there will be any issues with your existing configuration as you are currently running 15.0.

Thank you Rajan!

I am going to upgrade it tonight, and will keep you posted.

Once again thank you
