Почему Нету аудио в исходящих звонках через SCCP? - вопрос №2988589

Доброго времени суток!
Настроил SCCP телефоны Cisco Ip Phone 7942 с помощью chan_sccp Asterisk в FreePBX, но есть проблема:
Можно звонить и звонки проходят и принимаются, но нету исходящего звука, т е я слышу, но меня не слышит. В чем может проблема?
