i have configured gateway for making calls but it dosn't work;
my config files are as follow:

first create file that name " iptel.org.xml " in the below path:
 /usr/local/freeswitch/conf/sip_profiles/external/
i have an account on iptel.org like :(username:aimas;password:mypass)
  
<include>
<gateway name="custom">
<param name="username" value="arimas"/>
<param name="password" value="mypass"/>
<param name="realm" value="iptel.org"/>
<!-- iptel.org requires a 'proxy' parameter -->
<param name="proxy" value="sip.iptel.org"/>
</gateway>-->
</include>
             
the run :
sofia profile external restart reloadxml reloxm
and sofia status:
 Name          Type                                       Data      State
