What is happening is the time interval for your bri interface to come up to
send your pings across. A couple of options is to increase the dialer idle
timeout command or perhaps configure a default ip route to the remote site
with the interface being the default gateway. forexample:
ip route x.x.x.x x.x.x.x dialer0
if you have a static route pointing to a ip address, it will definately
cause a slowness for the interface to come up. Another option is to leave
the interface up, but this is usually not a viable solution.
