User has a Cisco 881 router at home connecting to the Internet on the outside and a company provide PC\IP phone on the inside.
This home router has a EZVPN tunnel from it to the Corporate Hub site which has a 3925 that is acting as the head-end router.
Users are complaining about voice quality issues.
One thing I have found odd is that, from my PC, if I ping traffic that has to go THROUGH the tunnel to the SVI on the remote 881 router (10.x.x.x range), I loose packets fairly often... BUT, if I have another parallel ping going to the public IP of that remote router, I loose Zero pings...
So it appears that this issue isn't related to the circuits
Could EZVPN be renegotiating tunnel settings every so often and that is causing the dropped pings through said tunnel and ultimately the VoIP quality issues?
Thought you might like to know that the problem appears to have been related to the fact we apparently didn't have CEF enabled on the head-end router... Once we enabled that the ICMP drop's and voice quality issues went away!
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
