Hello Maksym
It seems that Legacy Dial-on-Demand routing (DDR) is configured on the router. This means that one or more of the following commands are enabled on the router:
In Global Configuration mode:
dialer dtr or dialer inband <em>parity</em>
On some interface:
dialer string ...
dialer map
dialer-list
dialer-group
dialer enable-timeout
dialer wait-for-carrier-time
dialer priority
Check both physical and virtual (dialer and otherwise) interfaces for any such configurations and remove them.
You might find some additional information here: http://www.cisco.com/c/en/us/td/docs/ios/12_2/dial/configuration/guide/fdial_c/dafspoke.html#wp1000999
I hope this has been helpful!
