Односторонний RTP Опции

[pistonov]

Добрый день.
После некоторого времени нормальной работа "зависает" RTP на аппаратах IP8802a. На входящем или исходящем вызове RTP поток идет только от станции (астериск) к аппарату. Трафик разрешен. После перезагрузки телефона слышимость восстанавливается. Вот дамп с интерфейса станции в момент "зависания":

10.77.10.1 - АТС
10.44.4.210 - IP8802a
