Elastix, 2 локальные сети, DVG-7111S

Доброго времени суток! Есть такая проблема: установлен Elastix, воткнуты две сетевые карты, одна смотрит в сеть 192.168.1.0/24, другая - 192.168.15.0/24. В сети 192.168.1.0 находятся пользователи, из второй сети приходит только телефонный номер от DVG-7111S. При входящем звонке на DVG-7111S все работает нормально. При исходящем - связь рвется через несколько секунд соединения. Подскажите куда копать.
