Ring Detection Timeout

The operation of Ring Detection Timeout depends on the following:
No automatic dialing and Caller ID is enabled: if the second ring signal doesn't arrive
for Ring Detection Timeout, the device doesn't initiate a call to the IP.
Automatic dialing is enabled: if the remote party doesn't answer the call, and the
ringing signal stops for Ring Detection Timeout, the FXO releases the IP call.
Ring Detection Timeout supports full ring cycle of ring on and ring off (from ring start to ring
start).

FXO Supplementary Services

The FXO supplementary services include the following:
Hold / Transfer toward the Tel side: The ini file parameter LineTransferMode must
be set to 0 (default). If the FXO receives a hook-flash from the IP side (using out-of-
band or RFC 2833), the device sends the hook-flash to the Tel side by performing one
of the following:
•
Performing a hook flash (i.e., on-hook and off-hook)
•
Sending a hook-flash code (defined by the ini file parameter HookFlashCode)
The PBX may generate a dial tone that is sent to the IP, and the IP side may dial digits
of a new destination.
Blind Transfer to the Tel side: A blind transfer is one in which the transferring phone
connects the caller to a destination line before ringback begins. The ini file parameter
LineTransferMode must be set to 1.
