配置网关

			
[root@netkiller ~]# cat > /etc/freeswitch/sip_profiles/external/hamsoverip.xml <<EOF
<include>
	<gateway name="hamsoverip.com">
		<param name="username" value="300177"/>
		<param name="realm" value="pbx-ap.hamsoverip.com:5160"/>
		<param name="password" value="178aee323ef95"/>
		<param name="register" value="true"/>
		<param name="register-transport" value="udp"/>
	</gateway>
</include>
EOF
			
		

配置拨号规则

			
[root@netkiller ~]# cat > /etc/freeswitch/dialplan/default/hamsoverip.com.xml <<"EOF"
<include>
	<extension name="hamsoverip.com">
		<condition field="destination_number" expression="^300(\d+)$">
			<action application="bridge" data="sofia/gateway/hamsoverip.com/300$1"/>
		</condition>
	</extension>
</include>
EOF
			
		

再举一个例子, 0 作为外拨号码

			
cat > /etc/freeswitch/sip_profiles/external/netkiller.xml <<EOF
<include>
	<gateway name="netkiller.cn">
		<param name="username" value="6000"/>
		<param name="realm" value="sip.netkiller.cn:5060"/>
		<param name="password" value="6000"/>
		<param name="register" value="true"/>
		<param name="register-transport" value="udp"/>
	</gateway>
</include>
EOF

cat > /etc/freeswitch/dialplan/default/netkiller.cn.xml <<"EOF"
<include>
	<extension name="netkiller.cn">
		<condition field="destination_number" expression="^0(\d+)$">
			<action application="bridge" data="sofia/gateway/netkiller.cn/$1"/>
		</condition>
	</extension>
</include>
EOF
