возврат после перевода звонка. parabel asteroid + elastix 2.0.3

// UPD Сброса как такового нет. Если после появления шумов нажать снова Flash, звонок корректно возвращается. Т.е. во всей операции перевода-возврата появляется еще одно лишнее нажатие Flash после появления шумов. Шумы появляются в принципе, если поставить звонок на удержание и вернуться обратно.

Здравствуйте,

Есть одна инсталляция из Asterisk 1.6.2 на базе Elastix 2.0.3 + банк каналов Parabel Asteroid 8FXO/22FXS. Все работает корректно за исключением одного момента. Сбрасывается звонок при возврате после перевода звонка, если абонент оказался занят. Поясню на примере:

1. DAHDI/18 звонит на DAHDI/1
2. DAHDI/1 нажимает FLASH для перевода звонока на DAHDI/2
3. DAHDI/2 оказывается занят
4. DAHDI/1 снова нажимает FLASH, что бы продолжить разговор с DAHDI/18
5. Происходит сброс
