Hi,
I know this sounds silly and may cause argument but there is a littlie on I
would try.
We found a number of 1600's and 2600's seemed to play up in this manner.
Try creating a dialer interface rather than hard configuring the BRI. You
can avaiod some of the issues. Another advantage of using dialer interfaces
is that you can alter (creat a different one) without having to drop your
existing service. In this way you can more easily make changes remotely.
Also there are some bugs when using multiple BRI channels you can overcome
using dialer maps. For example setting up a class for the dialer idle
timeout which in some IOS versions will revert back to 120 seconds on second
(third channel etc).
The 20 seconds often inicates an issue finalising the connection and tying
the dialer map to an IP address. (username to the IP address)
Just some thoughts.
