Пропадает голос от собеседника через SIP Интертелеком

Elastix 2.2.0. Подключили SIP от Интертелеком и наблюдается часто пропадание голоса входящего собеседника, он нас по прежнему слышит. Подключено 4 разных номера, на всех одна и та же проблема. Но на одном это происходит через 5 минут, на другом - через минуту, может в начале разговора.

Сервер не за натом, белый айпи. Никакие порты в сторону инета не режутся. Трасса до сервера отличная:
