Hi all,
We have an asterisk version v1.6.1.20 with a TDM400 board (2 FXS and 2 FXO).
We want to do, transfer “blind” and “attended” from a line external connected to one FXO.
We configured, and transfers from internal lines (FXS) work fine but from (FXO) not.
We have made 2 test, one work fine from FXS and the other form FXO no.
Test 1, work fine:
- A (FXS-1) — call ----> B(FXS-2)
- B (FXS-2) digita #1 (blind transfer) after that press dtmf 9 (to dial FXO-1).
- B hungup.
- A ---- connected to ---- linea externa FXO-1.
Test 2, did’t work.
- A (FXS-1) — call ----> B(FX0-1)
- B (FX0-1) digita #1 (blind transfer), listen tone and when press any dtm the call hungup.
Bellow you can see, log when we try a blind transfer from FXO.
