Маршрутизация SIP звонков без авторизации на CGP

Добрый день!
Никак не могу разобраться.
У меня есть АТС, она через SIP пытается работать с CGP. Так вот вопрос в следующем, как позволить ей совершать звонки через CGP, без авторизации на нём. Т.е. схема должна быть следующая:
АТС --> CGP --> шлюз провайдера.
Связка (CGP --> шлюз провайдера) работает. АТС находится в Лан, соответственно - LAN:[192.168.10.115] is Trusted

Лог звонка:
