Hi,
I have a client has a Cisco 2600 router configured with ISDN callback for one of their users. On their last bill from the telco they saw that during the callback session, another 0,04 Norwegian kroner was charged about every 30 sec. during the callback connection was established and running. Just wondering if the router is doing something it shouldn't as I find it strange that it makes a call attempt to the callback phone no. when it already is established.
Would like a second oppinion. Can anyone look at the config below and see if anything concerning callback is either wrong and/or be the reason for the problem?
My experience rather sketchy when it comes to remote access routers.
