30 секунд тишины после отбоя, ipLDK100-Asterisk по PRI Опции

[kurstas]

Схема подключения такая:
ipLDK100 --- E1 PRI ---- Asterisk ---- все остальные АТС (город, корпоратив, мобильные и т.д.)
На LDK включен DID, чтобы с астериска можно напрямую было вызывать абонентов LDK.
Абонент 139 прописан в LCR (типа, внешний), абонент 163 там не прописан.
Делаю следующее. Звоню со 163 на 139. Вызов со 163 уходит на астериск, астериск вызывает 139, LG получает вызов на 139, поднимаю трубку на аппарате - все ОК: абоненты соеденены. Кладу трубку на 139, а у 163 30 секунд тишина в трубке и только потом появляются короткие гудки. В других сочетаниях (первым положит 163 или вызов пришел извне (139)) тишины нет, короткие гудки сразу.
