Уважаемые, помогите пожалуйста, второй день бьюсь :(
есть cisco 827-4v и cisco 1750 с 2мя голосовыми портами
когда звоню с cisco на другую cisco звонок есть, а голоса не слышно :(
притом со стороны 827 sh voice call summ выдает

PORT         CODEC    VAD VTSP STATE            VPM STATE
============ ======== === ==================== ======================
1             -         -  -                     FXSLS_ONHOOK
2             g723r63  n  S_CONNECT             FXSLS_CONNECT
3             -         -  -                     FXSLS_ONHOOK
4             -         -  -                     FXSLS_ONHOOK

а со стороны 1750

PORT        CODEC    VAD VTSP STATE            VPM STATE
=========== ======== === ===================== ========================
2/0         None      n  S_CONNECT             FXSLS_CONNECT
2/1         -         -  -                     FXSLS_ONHOOK

в поле CODEC почему-то стоит None...

если звонить в пределах одной cisco (любой), то все слышно.

IP пакеты ходят в обе стороны и не фильтруются.
конфиг cisco 827-4v
