Call completion signaling問題

各位好,
本人的設備如下
1.
Elastix 2.3
Analog DID Line
TDM410P
Trunk Type : look start
Service Type : Wink
Signaling Type : DTMF
Phone: linksys 921
2.
Avaya S8300 CM5.2.1
MM711 Analog board
Trunk type: DID
Service Type: Wink
Signaling Type: DTMF
Phone Avaya: 9610,4621,2420
請問當我用一個手提電話通過Telco打進去一個Analog DID, asterisk接收到Call時直接派去DID extension, 在Asterisk 內己看見Call己進行對話,兩個電話也能對話,但手提電話顯示那個Call還在撥號中,過了大約50秒,那個Call會斷線,請問有人遇見過這個問題嗎??本人懷疑是Asterisk 沒有退回一個訊號回Telco,在外國找到一些資料
[The “wink” is a voltage reversal, lasting approximately 200ms, which the board sends to the Telco side after
that side has “seized” the line in preparation to send a call to the board; the “wink” tells the Telco provider that it’s OK to send the DID digits down the line]
在Avaya System內沒有這個問題,只在Asterisk內發生,Digital DID MFCR2內有forwards backwards(A,B bit),請問Analog DID有類似的東西要設定嗎,有人認識Analog DID 嗎??
