851 with IP Phone

Unanswered Question
Nov 16th, 2007

have 851 with ez vpn at home (pppoe/dhcp).

cisco ip phone keeps unregistering and my guess is that the tunnel is going down as there is not enough data passing.

is there any way to deal with this?

I have this problem too.

Try adjusting the TCP MSS on the router with the command ip tcp adjust-mss on interface BVI1 and see if that helps
