ISR4451 losing dial-peer configuration after upgrade

Hi

We have VoiceGateway with E1 line.

Problem we are facing with Voice gateway is, pots and voip dial-peer commands are disappearing after we upgrade. Our operate process is : firstly, we downgrade from the 03.16.05.S.155-3.S5 to 03.15.04.S.155-2.S4, and then upgrade from 03.15.04.S.155-2.S4 to 03.16.06.S.155-3.S6.

when we upgrade the 03.16.06.S.155-3.S6, all the dial-peer commands disappears.  so, we downgrade the current version 03.16.05.S.155-3.S5 and brush into the configuration manually. The first attach is current show tech infor, the second is the fault infor. And why we downgrade and upgrade is that we hit a bug before(CSCvc56422).

Always upgrade to the latest code available to remedy defects etc. I will have to look into if you might be running into another defect at the upgraded code but 15.X is pretty old now.

Thank you! any defect in this process?
