Kamailio+rtpproxy. Разные IP для signaling и RTP

AnnaK · June 27, 2014

Доброе время суток всем.

Eсть sipproxy kamailio+rtpproxy.

Kamailio отказывается слать sip и rtp пакеты на разные ip адреса (это требует свич, к которому он подключен).

SDP со свича корректные. В полях Owner/Creator, Session Id (o) и Connection Information © он присылает kamailio IP, на которые ждет rtp трафик. Но kamailio упорно продолжает стать rtp на signaling IP.

Кто-нибудь с этим сталкивался?

Логи сильно ускорят ответ. Желательно ещё с wireshark.

Это 5, приложите атачем файл *.pcap :-) Попытка #2 сообщение удаляю.

AnnaK · June 30, 2014

При попытке приложить *.pcap Ошибка "Вы не можете загружать файлы подобного типа".

Что нужно сделать, что бы загрузить файл?

Подозреваю, что можно добавить его в zip архив или переименовать в jpg.

r - flags that IP address in SDP should be trusted. Without this flag, rtpproxy ignores address in the SDP and uses source address of the SIP message as media address which is passed to the RTP proxy.

Спасибо, громадное! Помогло!

Буду внимательнее читать документацию...)

Кстати по дампу видно, что от свича в ответ на INVITE сразу идет обратный вызов, это так просто совпало или какая-то фишка SI3000?
