[inet-admins] cisco 1750 and netmeeting: help needed



Коллеги,

Вполне  допускаю,  что  это  known-issue,  но  поиск в инете абсолютно
ничего не дал.

Есть PC с WinXP SP2 с NetMeeting и циска 1750. Оба девайса находятся в
одном сегменте. У циски два интерфейса FXO, оба включены в офисную PBX
Multicom MP80 в абонентские порты.

При  звонке  на netmeeting с местного телефона (подключенного к той же
АТС)  или с него на местный телефон, отсутствует звук в направлении от
телефона  к  netmeeting'у.  Т.е. абонент на обычном телефоне прекрасно
слышит абонента на NM, а вот абонент на NM ничего не слышит.

NM  настроен  согласно  цисковой  доке: кодек - u-Law, циска прописана
шлюзом.
Конфиг циски и пр. ниже:
