Схема:
router0 ------ router1 ------- router2
Проблема:
Забиваем канал под завязку с router0 на router2 или с router0 на router1
Голос с router0 на router1 все нормально, а с router0 на router2 булькает
В чем может быть дело???
звонить разрешено только с router0 на router1 или router2
Предположение:
Может голосовой трафик притормаживает на router1 по каким то причинам
конфиги:
