Voip Call Protocol Setup - Soundwin VoIP Voice Gateway User Manual

3.3 VoIP Call Protocol Setup

Step1 : Configure VoIP Call Signal Protocols :
User could select H.323 or SIP Protocol, and click "select"
Step2 : configure the numbering with phone/line ports.
Phone Number (FXS): The representation number is the phone number of the telephone
that is connected to Phone port.
Line Number (FXO): Line ports are connected to the extension ports of the PBX system or
the PSTN line. They have a common Line Hunting Group Number. When this number is
dialed, the Gateway system will find a free FXO line connected to PBX. This hunting will skip
all busy lines and absent lines and find only the idle line to the PBX. After the available line is
found, you can hear the dial tone from PBX. After that, you can dial the needed phone
number out through PBX.
Step3: Let GW Register to Gatekeeper(GK)/SIP Proxy Server
(If user does not have GK/SIP Proxy Server, Please go to Step 4: Outgoing Dialing Plan)
Gatekeeper IP address: There is a gatekeeper address fields. If this gateway does not want
to register to any gatekeeper, just set value 0.0.0.0 to the primary gatekeeper address.
SIP Proxy Server IP addresses: There is a SIP Proxy Server address fields. If this gateway
does not want to register to any SIP Proxy Server, just set value 0 .0.0.0 to the sip proxy
server address.
Step 4: Outgoing Dialing Plan
The purpose of "Outgoing Direct Call" setting is to let user create a proprietary dialing plan
when this Gateway is not registered to any H.323 Gatekeeper or any SIP Proxy Server. This
setting can also assign some dialing plan to local ports (including prefix strip, prefix
addition).Through this setting, user can directly map a number to a specific gateway (IP address).
In the "Outgoing Dial Plan" settings.
