Hi Akram, 

I have faced many abnormal issues with the SIP phones registering to the Cisco CME. But most of my issues got solved using this method. 

Check your CME version by #show telephony-service. Then downgrade or upgrade the Cisco IP Phone firmware as compatible with the same version. I am giving you the example of my scenario which I did back then. I was using the same ISR4300 Router with CME 10.5. I downgraded my IP phone firmware to match this guide...

As I see your Phone firmware, they are among the latest like mine. But after downgrading the firmware as in the sheet, my issues were resolved Alhamdulillah.

Let me know if this resolves your issue.

Can you share me the #show telephony-service output? 

There is no 10.3.1 in the compatibility matrix page for the CME. Maybe you can check with the 10.0 version. Or you can double check your CME version and then choose from the following link.

I hope this will resolve your issue. Please let us know the status.

Sorry for late reply. I have been busy.

The different iOS versions for ISR 4351 can be found here. I will sugggest to download the latest suggested by the Cisco because many bugs are fixed and it has latest features.

The upgrade of iOS is same like others. You can follow the below guide to upgrade the iOS of your router which will have the updated CME.

Can you please attach o/p of "show voice register global", and please take these logs during issue "debug ccsip message", "debug ccsip error" & "debug voice register events" and attach here.

I would upgrade the cme/ios version on router to latest available version if not done yet.
