Cisco C887VA-K9 Connectivity Block

Level 1

Hi everyone,

I have problems with the Cisco887va-k9 router. I use this for connettivity adsl2+ or vdsl. After about 10 days this router goes to block, I can not ping it but the adsl or vdsl session is always up! Of course I have to reboot the router to restore connectivity. Have you had any similar problems? I use this especially for voip connectivity, but I do not know where the problem may be.

This is my configuration for VDSL.
