ISR4K CUBE w/ LTI Xcode - Intermittent Call Drop with cause code 47

[Computacenter NS Tech. Support]

Hello

According to TAC, we hit that bug CSCvg17981 on ISR4k/CUBE with OS 17.x

Is there here  anyone found a workaround or a way to mitigate the issue ?

We have a 600 SIP channel customer impacted and will be gratefull to hear any idea , before Cisco provides us a fix.

nb: periodic ISR reload just lower the impact and not solve the issue

Issue on ISR4451-X / CUBE  tested with  17.4.1d and still there after downgrade to 17.3.3 MD
