Aaron,
Thanks for the advice.
Most of my locations are in different states, therefore the long distance
charge of being on all the time will not do.
I just thought there might be some time frame or something like that which
was dropping the connection. I was hopping to bumping that time limit up to
like 2 hours or something. If it is really lack of traffic I could see that
being a problem at one of our locations. All the other locations have
people hitting that all day long. Of course the one I did first was the
smaller location which could be not sending traffic for an hour or so at a
time.
I am going to order another 1811 and do what you suggested about the
debugging. I will just set it up for one of the other locations and test it
here before I send it out.
Thanks again,
Jason Baker

Jason,
Debugs are your friend. I would NTP sync my routers, configure msec
timestamps (service timestamps debug date msec), create good sized
logging buffers (say, logging buffered 500000 debug). Then turn on the
following debugs to see what's happening:
debug modem
debug dialer
debug ppp nego
Then when a given site disconnects, look at the debugs at this time from
the central and remote and see what they tell you.
Your configs on on the router will also be relevant. If you don't like
your calls dropping, then why not configure your backup links always to
be up (while the primary path is down)? (Hint: consider using dialer
watch.)
Regards,
Aaron

~ To the Cisco people who know best,
~
~ I currently have a 2811 (Corporate) router and a 1811 (Remote) router.
The
~ 2811 has an eight port analog card in it for supporting all of my
locations

Async
~ connection dropping many times during its "connection" period. If I
unplug

the
~ 2811 router and traffic will work fine for a while. I configured the
backup

~ During a three hour period of being down, the Async went down and backup
17
~ times with time frames of being up from 3 minutes to 20 minutes. Of
course

is
