Здравствуйте.

Есть следующая схема:

мини АТС - isdn pri - Cisco 2811 - ethernet - различные VoIP клиенты (AddPac и AudioCodes).

так вот звонки со стороны АТС на клиентов проходят в кодеке G.711, а вот с клиентов на АТС только g.729. Как организовать прохождение голоса с кодеком g.711 от клиентов на АТС?

p/s - самое странное что от клиентов даже сигнализация не проходит сразу идет отлуп(если физически указать шлюзу отправлять только g.711)

Ниже привожу данные:
