I use a version of 11 and 13 - no result.
There is method for solving?

My PBXs has been updated with AsteriskNOW.
Now I installed on the test stand PBXs FreePBX-64bit-6.12.65 the downloaded from the site of the ISO file.
On the stand there is no problem.

Why is that?

^^^^^^^^^^^^^^^^^^^^^^^

OK. I change the settings deleted. You need a dump?

Any help ?
One solution - reinstalling FreePBX Distro and transfer configuration.

Run asterisk-version-switch

Thank you all!

I found an error. Ago I tried to install from a source spadsp.
After manual removal of it worked.
