Output for "show isdn status". Was this working before ?

Not, it is configure on clear system

#sh isdn status
Global ISDN Switchtype = primary-net5
ISDN Serial0/1/0:15 interface
        dsl 0, interface ISDN Switchtype = primary-net5
    Layer 1 Status:
        ACTIVE
    Layer 2 Status:
        TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
    Layer 3 Status:
        0 Active Layer 3 Call(s)
    Active dsl 0 CCBs = 0

    Number of L2 Discards = 0, L2 Session ID = 30
    Total Allocated ISDN CCBs = 0

Ok. That looks fine. Enable the following debugs and collect logs for failed call -

debug isdn q931
debug voice ccapi inout

I added debug commands, but debug messages i not see.

If i call on one number communication at once are closes (is heard shortly beep), if i call on another number from E1 flow i hear long beep (as normal call when long time no answer on call), but logging messages i not see as before.

Do a "show logg" if you are collecting them in a buffer.
