Hello community,

в результате организации DialUp доступа с CallBackom, наступил на
следующие грабли:

Ошибку видно, но вот какова причина этой ошибки не могу понять. На
какой девайс ругается функция?
В двух словах о том что происходит: дозваниваюсь, модемы вяжутся,
проходит аутентификация, после чего запрашивается номер для перезвона,
обрыв и виндовая машина ждет перезвона, но...
При отключении CallBack PPP работает нормально.


Система: AltLinux Master 2.4
пакет PPP: ppp-2.4.2-alt6 (пробовал и на ppp-2.4.2-alt2 и на
ppp-2.4.1-asp3)
