） 
the user dial all the number for one time, such as 962304138;
2
） 
Receiving the call, R32 will extract the callee number from the signal message,
and change the number according to trunk group routing table. For example, if the
“ChangeType” is “DelPrefix” and the “ChangeLen” is “2”, 962304138 should be
changed into 2304138;
3
） 
R32 will choose one available FXO port, off hook, and send 2304138 to PSTN
switch.
Cautions:
1
、
At first, in IP-FXO phase, no matter the Routing Direction is P2P IP Route or
Register IP Route, it must be guaranteed that the call can be reached. Under
one-stage mode, the callee number of IP-FXO call request may not be the same as
the register number of FXO port, so some servers may not let it pass the call
authentication.
2
、
When R32 automatically send the number to PSTN, the cooperation with PSTN
switch may have trouble. If send the number too fast, and PSTN switch is not ready,
the opposite side can not receive the total number; If the interval of sending number
is too small, and the detection sensitivity of switch is not high enough, the opposite
side can also not detect the total number. R32 provides 2 parameters: “Regenerate
DTMF Digit Interval” and “Regenerate DTMF Digit Delay”, which can help further
adjust the cooperation with PSTN switch in sending number under One-stage mode.
In fact, the time point of sending DTMF number to PSTN line can be identified through
dial tone detection theoretically. But because the dial tone detection itself has a very high
requirement on the compatibility of the product, is very complicated in realization, and also
need a detection delay, so currently R32 does not do so.
Main configuration:

Step 1: Basic Configure ---> Port ---> Port Configuration ---> set PhoneNbr, such as 9
( refer to section 5.3.2 );

Step 2: NBR Exchange ---> ChangeRule ---> Number Change Rule Table: such as
delete prefix in one number (refer to section 5.5.3 );
 Step 3: NBR Exchange ---> RegenNBRChange: configure number change rule of
One-stage mode corresponding to FXO port (refer to section 5.5.6 );
 Step 4: Advanced Configure ---> FXO: set “Regenerate DTMF Digit Delay” and
“Regenerate DTMF Digit Interval”. Normally you can use the default value (Refer to section
5.4.2 ).
