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:
