You did not attach the complete configuration. Since this is an ISR-4k, the clocking is a bit different than the previous gen ISR's.

Do the following -

network-clock synchronization automatic
no network-clock synchronization participate 0/1

Do a "clear counters" and then monitor the slips.

Hi,

Thanks for the reply , 

The file is quite long due to the fax dial peer configuration , and I sanitized the user infos ,

It would be great if you could say which important information are  missing in the config file 

Thanks 

[R0g22]

I already highlighted the changes that need to be done. Please check my last post.

[Daniele Giordano]

Slips are sync errors.

Do you have try these commands?

network-clock-participate

network-clock-select

Regards.
