title: SIP extention created by FusionPBX can not login into softphone
body: <p>I have a <code>FreeSWITCH</code> v1.6.13 on my Debian 8( From git) and it is OK.
  After that i installed the last <code>FusionPBX</code> to manage my PBX telephony <code>FS</code>.
  But it gives me error : 403 You must define a domain called x.x.x.x in your directory...
  Both i installed by FusionPBX guid in their web site.
  <a href="http://fusionpbx-docs.readthedocs.io/en/latest/additional_information/freeswitch.html" rel="nofollow noreferrer">FreeSWITCH</a> and <a href="https://www.fusionpbx.com/download.php" rel="nofollow noreferrer">FusionPBX</a>.
  Im going crazy cause about 4 days i Am working and not a good result yet.
  I know Fusion store data in DB and i give him a Pgsql user name and password.( not the default one it suggest after ./install command) and also FS with --enable-core-pgsql-supprt in ./configureaiton with -C.
  And i searched a lot, and all says as this link.
  But when i go to sip status from FusionPBX, it says that my ip is correct, and also i did what they say but no success.
  Just one time it worked! and i did not why it work.
  And after it does not work and again says 403 you must ....
  And after that i create an extention, i go to FS terminal and type user_exist 101 (user i created in fusionpbx)it return me false.
  Can it be DB issue?
  I do not know why just one time it worked and after i after that again gave me 403 error.
  Cause i did changed a lot i could not understand what was the cause to work it.
  Is it a bug?
  What exactly i am doing wrong??
  Really any help will appreciate.</p>
  
  <p>EDIT 1 :
  My softphone is android zoiper for test the created extention in fusion.</p>
