VoIP DLG Refresh Intvl
Interval between (SIP) Dialog refresh messages sent by the SPA to detect if
the VoIP call-leg is still up. If value is set to 0, SPA will not send refresh
messages and VoIP call-leg status is not checked by the SPA. The refresh
message is a SIP ReINVITE and the VoIP peer must response with a 2xx
response. If VoIP peer does not reply or response is not greater than 2xx, the
SPA will disconnect both PSTN and VoIP call legs automatically. The range is
0-255.
The default is
30
.
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 Dial Digit Len
Determines the on/off time when transmitting digits through the FXO port.
The syntax is
on-time
/
off-time

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 Linksys 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.
