СвязьПроект

При дозвоне с FXS на SIP(SIPNET), соединение устанавливается. С SIP(SIPNET) на FXS звонок проходит(!!!), а после поднятия трубки тишина и секунд через 5 SIPNET обрывает связь. Подскажите пожалуйста в чем может быть проблема. Заранее СПАСИБО.

Добавьте в sip-ua еще:

remote-party-id
и user-reg

Перерегестрируйте на сервере.

Спасибо, попробую.
