Possible Cause Solution
1.
The PBX does not detect hook-
flash signals when using DTMF
or SMDI voice mail interface.
Ensure that the following has been configured:
LineTransferMode = 1.
For FXO interfaces only: Modify the parameter
FlashHookPeriod according to the PBX requirements.
This parameter determines the hook-flash generation
period (in msec). The valid range is 300 to 1,500 (default
is 400).
For digital interfaces only: Ensure that the
TrunkTransferMode_x = 3 (for CAS Normal) or 1 (for
CAS NFA).
