Ubuntu 14.04, Asterisk 11.11.0, Freepbx 12

Пытаюсь прикрутить новый астер, вместо 1.8, но Asterisk молчит:

Часть конфига за звуки:

$ cat asterisk.conf
[directories]
astdatadir => /usr/share/asterisk
[options]
languageprefix = yes
defaultlanguage = en
documentation_language = en_US

Хотя:

$ ls -l /usr/share/asterisk/sounds/en/silence/1.gsm 
-rw-r--r-- 1 root root 1650 Oct  5  2011 /usr/share/asterisk/sounds/en/silence/1.gsm

Что еще проверить? Почему не воспроизводит?

p.s. Сам звонок:
