When using the callback mechanism, you should use the following
settings, to
avoid call collisions on the line:
Case 1: BRICK is initiating the Callback
----------------------------------------
-connect to the BRICK with telnet or serial
-edit the "biboppptable" of your WAN partners interface
-set "Maxretries" to "1", e.g.
MaxRetries:01=1
-set "Blocktime" to a value greater than "10"
Case 2: BRICK is doing the Callback
-----------------------------------
-connect to the BRICK with telnet or serial
-edit the "biboppptable" of your WAN partners interface
-set "Callback" to "enabled"
-set "MaxRetries" to "5", in any case use a
value greater than "1"
