Dear all,
I am configuring a cisco 1841 modular to connect to clients' network
using ISDN basic-net3. I have done all the configuration and after I
restart the router the BRI is able to dialout using the dialer
profile, reaching to username authentication and then disconnect the
connection (as expected). However, after idle for some time, I cannot
dial out at all. I receive unfound B channel error message. I have to
reconnect the ISDN connection or do shut/noshut on the int Bri0/1/0.
then it connect and perform up to the authentication.

I need to know where to begin the troubleshooting and i have pasted
the config and error message for "unfound B channel".

I badly need help, please.

Below is the snipet of the config:
