avaya 1110 + asterisk

Приветствую. Появилась задача подключить некоторое кол-во аппаратов к астериску, до это с ними не сталкивался. В процессе возник 1 вопрос и одна (пока, гы) проблема. Вопрос - где можно найти описание параметров файлов провизионинга, в основном попадаются куцые примеры без особоых комментариев.

Проблема. Нет звука при звонках с/на/между аваями. Телефоны зареганы, в unistim.conf прописаны, звонки ходют, а вот звука нет. Все находится в одной локальной сети, фаервол выключен. Астериск 1.8.20

unistim.conf выглядит так:

[general]
port=5000                    ; UDP port
autoprovisioning=yes
qualify=yes
disallow=all
allow=alaw
allow=ulaw

Что делать? P.S. С rtp_method играть пытался, но в слепую без описания (не нашел, может кто подскажет где есть) что к чему результата не принесло.
