PSTN Ring Thru
Delay
Delay in seconds before starting to ring thru Line 1 after the
PSTN starts ringing. In order for Line 1 to have the caller-id
information, the delay should be set to larger than the delay
required to complete the PSTN caller-id delivery (such as
5s). The range is 0-255.
The default is 5.
PSTN-To-VoIP Call
Max Dur
Limit on the duration of a PSTN-To-VoIP Gateway Call. Unit
is in seconds. 0 means unlimited. The range is 0-
2147483647.
The default is 0.
VoIP-To-PSTN Call
Max Dur
Limit on the duration of a VoIP-To-PSTN Gateway Call. Unit
is in seconds. 0 means unlimited. The range is 0-
2147483647.
The default is 0.
PSTN Dialing Delay Delay after hook before the SPA dials a PSTN number. The
range is 0-255.
The default is 1.
PSTN Ring Timeout Delay after a ring burst before the SPA decides that PSTN
ring has ceased. The range is 0-255.
The default is 5.
PSTN Dial Digit Len Determines the on/off time when transmitting digits
through the FXO port. The syntax is on-time/off-time,
where on-time and off-time are expressed in seconds with
up to two decimal places, within the permitted range,
which is from .05 to 3.00.
The default is .1/.1. If this value is blank, the default is used.
PSTN Hook Flash
Len
The length of the hook flash in seconds. During a PSTN-to-
VoIP gateway call, the ATA device processes the out-of-
band hook flash signal sent from the VoIP peer through a
hook-flash (momentary on-hook signal) on the FXO port.
This allows the VoIP peer to initiate a three-way
conference call and subsequent call transfer. The duration
of the on-hook signal can be configured using this
parameter.
The default is 0.25. The permitted range is limited to 0.02
to 1.6 seconds.
