Предположительная потеря дескриптора соединения

Description

  1. Окончание FXO получает вызывной сигнал и отправляет вызов группе 803.
  2. Телефоны 101, 102, 103, 104 и 201 звенят.
  3. На телефоне 103 снимается трубка.
  4. Устанавливается соединение, остальные телефоны звенеть перестают.
  5. абонент 103 нажимает flash, однако признаков посылки REINVITE в логе нет, у окончания FXO по-прежнему остается активный RTP поток!
  6. абонент 103 получает CallDisconnect от FXO (неизвестно как сформированный).
  7. абонент 103 вызывает 102.
  8. аппарат 102 звенит.
  9. практически одновременно абонент 103 кладет трубку, абонент 102 снимает трубку.
  10. Устанавливается соединение 103 <--> 102.
  11. 103 получает CallDisconnect для нового соединения и отправляет BYE, который не доставляется прокси-сервером (Message failed).
  12. через некоторое время абонент 102 (который, видимо, ничего не слышал в трубке) кладет трубку.

В результате всего этого остается неотбитое соединение канального окончания FXO, которое при этом рефрешится по UPDATE/200 OK!

Судя по всему, при нажатии flash абонентом 103 соединение не было переведено на hold, но и отбито тоже не было. Оно осталось существовать в виде дескриптора соединения, "привязанного" к каналу 3, в то время как канал 3 об этом соединении ничего не знает.

При каждом рефреше сессии канал 3 получал уведомление о получении ответа 200.

По пункту 5: REINVITE был послан, но не дошел до получателя из-за ошибки прокси (No other DNS entries to try (7,111)). Это и было причиной одностороннего CallDisconnect, в результате которого канальное окончание FXS "забыло" о соединении, при том что дескриптор остался существовать.

Установлено, что иногда сообщения не проходят через прокси из-за того что по каким-то причинам прокси выбирает для отправки сообщения шлюзу транспорт TCP, которого у шлюза нет. Замечено, что это происходит довольно редко и касается только запросов.

Варианты решения:

  1. Добавить шлюзу транспорт TCP.
  2. Заменить шлюзу существующий транспорт UDP на транспорт TCP.
  3. Изменить настройки транспортов прокси-сервера таким образом, чтобы внешние (существующие) транспорты слушали только внешние адреса, и дополнительно добавить специальный транспорт для связи со шлюзом на адресе 127.0.0.1 в надежде что для отправки на адрес 127.0.0.1 всегда будет выбираться именно он.

Установлено, что в TransportSelector::transmit() иногда вызывается с target 127.0.0.1:6060 и протоколом TCP. Откуда происходит вызов, пока непонятно.

В качестве временного решения применен такой патч:

  • TransportSelector.cxx

    old new  
    822822
    823823      if (msg->isRequest())
    824824      {
     825         if(target.isV4() && target.isLoopback() && target.getPort() == 6060) {
     826            target.setType(UDP);
     827         }
    825828         transport = findTransportByVia(msg, target, source);
    826829         if (!transport)
    827830         {

Проблему потери сообщений из-за выбора неверного транспорта он решает.
