Thanks a lot.
I will upgrade my ISR.
By the way, as I have mentioned in other post that my I5141 is as below:
Spectre: sub-version 10.1.1.200.isr13
icfb: sub-version 188.8.131.520.6.132,
Could you please tell what is the latest hotfix for IC5141.
Whether, the latest hotfix would be comaptible to my very very very old ISR.
