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??
 
 
 Thanks,
