Step 1

edit vars.xml and it should look like this

  <!– Internal SIP Profile –>
  <X-PRE-PROCESS cmd="set" data="internal_auth_calls=true"/>
  <X-PRE-PROCESS cmd="set" data="internal_sip_port=5080"/>
  <X-PRE-PROCESS cmd="set" data="internal_tls_port=5081"/>
  <X-PRE-PROCESS cmd="set" data="internal_ssl_enable=false"/>
  <X-PRE-PROCESS cmd="set" data="internal_ssl_dir=$${base_dir}/conf/ssl"/>

  <!– External SIP Profile –>
  <X-PRE-PROCESS cmd="set" data="external_auth_calls=false"/>
  <X-PRE-PROCESS cmd="set" data="external_sip_port=5060"/>
  <X-PRE-PROCESS cmd="set" data="external_tls_port=5061"/>
  <X-PRE-PROCESS cmd="set" data="external_ssl_enable=false"/>
  <X-PRE-PROCESS cmd="set" data="external_ssl_dir=$${base_dir}/conf/ssl"/>

and

  <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G729,G723,G711U"/>
  <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=G729,G723,G711U"/>

Step 2:

All Termination GW will be added now under /usr/local/freeswitch/conf/sip_profiles/external

create gw.xml and it should look like this

<include>
        <gateway name="broadvoice1">
          <param name="username" value="4234685032 "/>
          <param name="realm" value="4234685032 "/>
          <param name="from-domain" value="174.136.52.143"/>
          <param name="password" value="sipsip"/>
          <param name="extension" value="5555551234"/>
          <param name="proxy" value="174.136.52.143"/> <!– example using the broadvoice DNS SRV record for New York City. –>
          <param name="expire-seconds" value="3600"/>
          <param name="register" value="false"/>
          <param name="retry-seconds" value="6"/>
        </gateway>
    </include>

 

Step 3:

Now create a Ingress GW

Goto/usr/local/freeswitch/conf/autoload_configs and edit acl.conf.xml

vi acl.conf.xml and add this in the bottom

<list name="asterisk_box" default="allow">
  <node type="allow" cidr="216.218.233.194/32"/>
</list>

now we have to apply this ACL in /usr/local/freeswitch/conf/sip_profiles/internal.xml

vi internal.xml

add this line at the bottom

<param name="apply-inbound-acl" value="asterisk_box"/>

Step 4:

Now create a Dial plan

goto /usr/local/freeswitch/conf/dialplan

vi public.xml

<extension name="outbound_international">
<condition field="destination_number" expression="7243(\d+)$">
<!–<action application="set" data="absolute_codec_string=G729"/>–>
<action application="bridge" data="{absolute_codec_string=’G729′}sofia/gateway/broadvoice1/7243$1"/>
</condition>
</extension>

Step 5

Now start the freeswitch and make the calls

Great tutorial! If anyone out there is interested in a FreeSWITCH Training, Darren Schreiber (co-author of the FreeSWITCH book) has started trainings throughout the world. The next training is in March in San Francisco. Check out http://www.voipkb.com for more details.

2. almond oil benefits - May 1, 2013

The skin is the largest organ of the human body and it has the ability to absorb the nutrients
contained within almond oil just by rubbing it onto your skin.

Babassu Oil is especially suitable for eczema, itchy, dry, and inflamed skin.

Unlike some treatment products, almond oil (being completely
natural), can be used as frequently as you wish.

3. moroccan oil - May 23, 2013

It is without a doubt the best solution for revitalizing your skin.
The oil is extracted from the fruit kernel of the Argan tree, which grows almost
exclusively in the southwestern region of Morocco. Prostaglandin is a natural anti-inflammatory and acts as a controlling factor in overall cell growth
and development.
