after test differents options i found the solution. Perhaps help to somebody too.
The first, but i do not know if it is necesary, I add in the queues.conf the line
Set (MONNITOR_OPTIONS=V(3)) ; In my case the problem it was recording the speaker.
The second and I think the solution it to change de codec used from G729 to U-Law.
Now it is working properly, inside and outside calls records.
