============================================
the router will drop the first 3 or 4 packets untill the isdn connection has established.
the isdn connection will be established in 4-5 seconds.
the customer has tested the same connection with a
3 Com Router --> the result was positive! the router has forwarded all packets correct..
do you have any other idea?? is there a ios problem?
thx
luigi
