3-d Party SIP Опции

[Зараза]

Есть eMG80. Зарегистрированы 112 - софт-фон на компьютере, 111 - SIP-DECT Panasonic KX-TGP500, 129 - Phontage Deluxe, 110 - аналоговый телефон. Все в локалке.

Проблема: не могу дозвониться на 111 с аналоговых телефонов eMG80.

Выход в город: 110, 111, 112, 129 - работает.
110 -> 112, 129 - все OK
129, 112 -> 111 - все OK
110 -> 111 - соединение не происходит, получаю отлуп.

вот в таком виде:

Не могу понять как проблема может быть увязана с тем, что инициатор проблемного звонка - аналоговый абонент.
