-codec
set who is the one to determine voice codec during
negotiation. 0 is caller will determine the codec, and 1 is
mater will determine the codec. (During negotiation 2
endpoints will compare gateway type level to determine who
is master.)
-gwprefix
drop or keep gateway prefix . “0” means when gateway has
incoming call from IP side, it will not drop prefix before
searching for callee number. “1” means when gateway has
incoming call from IP side, it will drop prefix before searching
for called number.
Note:
1. If user wants to implement one-stage dialing in FXO Line,
this function must be enabled, and user has to dial prefix
number (instead of Line number of FXO Line)+ PSTN
number to make a call to PSTN side connected with FXO
Line.
2. After gateway-prefix-drop function is enabled, user must
remember to re-configure line number of FXS Line,
because line number of FXS Line must remove prefix
number. For example, origin line number of FXS line is
1001, prefix is 100, since prefix number will be drop, once
gateway has incoming call 1001, after drop gateway prefix
100, it will search line number “1”. So line number must be
set as “1”.
-eod
It will transfer the DTMF in “#” if users disable the end of dial
function. Users have to press the key pad in “#” if the end of
dial function is enable.
-ring
ring time for ring detection(in ms). When Gateway has
incoming call from PSTN side to FXO port, Gateway will
determine it is a ring but not noise only if it is longer than this
ring time.
Note:
In Taiwan the ring time of PSTN usually is 1000ms, so if user
set ring time longer that 1000ms, FXO port may not be able to
pick up the call from PSTN side.
