Oh, my stupid mistake.
Sorry John, my brain stopped working that time.
I tried to type isdn callback in dialer interface :(
I tested isdn callback in legacy DDR and have the same result.
R8#
05:42:13: BR0 DDR: Caller id: Callback server starting to 666111
R8#
05:42:18: DDR: Callback timer expired
05:42:18: BR0 DDR: beginning callback to 666111
05:42:18: BR0 DDR: Attempting to dial 666111
R8#sh dialer
BRI0 - dialer type = ISDN
Dial String Successes Failures Last DNIS Last status
666111 0 1 00:00:09 failed Default
0 incoming call(s) have been screened.
7 incoming call(s) rejected for callback.
BRI0:1 - dialer type = ISDN
Idle timer (120 secs), Fast idle timer (20 secs)
Wait for carrier (30 secs), Re-enable (5 secs)
Dialer state is idle
BRI0:2 - dialer type = ISDN
Idle timer (120 secs), Fast idle timer (20 secs)
Wait for carrier (30 secs), Re-enable (5 secs)
Dialer state is idle
R8#
05:42:48: BRI0: wait for isdn carrier timeout, call id=0x8009
05:42:48: DDR: Freeing callback to 666111
R8#

>>
>> R8:

>> ppp callback accept
>> dialer string 666111 class CALLBACK
>> dialer remote-name R6
>> !
>> map-class dialer CALLBACK
>> dialer callback-server username
>>
>> 10) Finally test callback by having R6 call R8.
>>
>> 11) If this doesn't work, start back at step 1 ;-)
