"CCME не работает NAT"  +/
Сообщение от MichaelG (ok) on 23-Мрт-12, 11:25 
Добрый день!
Прошу помощи в решении возникшей проблемы.

Схема: CME(2911) -> cisco2811 -> SIP-Prov.

CME вызовы исходящие/входящие не работают. Не работает NAT или работает не правильно?!

CME:

CME шлюз VoIP провайдера видит и по адресу и по имени. Регистрация проходит успешно.

Если сделать интерфейсу СМЕ "белый" IP: xxx.yyy.zzz.214 то все работает замечательно.
Помоги чем сможете...

попробуйте добавить в sip-ua
nat symmetric role passive
nat symmetric check-media-src

у вас с регистрацией ок а медиапоток исходит от внутреннего интерфейса частной сети.

Именно с этим и воюю.
nat symmetric role passive/active - пробавал никак не отражается на натировании SIP
nat symmetric check-media-src

В данный момент ситуация такова:
Шлюз регистрируется у провайдера. Беру deb ip nat sip на 2811(Инет шлюз):
