Проблема сетевого вызова по SIP протоколу
Проблема сетевого вызова по SIP протоколу
Добрый день!
Проблема в работе SIP протокола.
Настроен SIP транк (без регистрации) между LG eMG800 и W&T-NS100.
Периодически не работает входящий сетевой вызов от LG eMG800 на W&T-NS100.
При этом в этот момент исходящий вызов от W&T-NS100 работает.
Статус линий СО и абонентов LG eMG800 в этот момент свободен.
По истечении определенного времени входящие на W&T-NS100 снова работают.
W&T-NS100 отклоняет входящий вызов.

Re: Проблема сетевого вызова по SIP протоколу
У вас порт указан 5060. А инвайт приходит на 30565. Вот станция и ругается

Re: Проблема сетевого вызова по SIP протоколу
на трассе форбиден. Это может быть несколько разных причин для доверительного транка
1. Несовпадение по портам
2. Инвайт приходит не с того адреса, что назначен
3. Станция забанила этот айпи адрес по каким-то причинам (слишком часто долбится, например)
Я бы начал с портов. сделай их одинаковыми и посмотри

Re: Проблема сетевого вызова по SIP протоколу
Сделал порты udp на обеих станциях одинаковыми. Проблема осталась.
