====== Using FreePBX with SDF VOIP ======

This tutorial shows how to add your SDF VOIP extension as a trunk in [[https://www.freepbx.org/|FreePBX]].

===== Prerequisites =====

  * A working FreePBX setup
  * Access to the FreePBX admin interface

===== Procedure =====

In the admin interface follow these steps, replacing ''$EXTENSION'' and ''$PASSWORD'' with your extension number and password respectively:

  - Go to //Connectivity// » //Trunks//
  - Select //Add Trunk// and choose //Add SIP (chan_sip) trunk//
  - Set //Trunk Name// to ''sdf''
  - Set //Outbound Caller ID// to ''<$EXTENSION@sip.sdf.org>''
  - Set //CID Options// to //Force Trunk CID//
  - Go to the //sip Settings// tab
  - Set //Trunk Name// to ''SDF''
  - Set peer details to:<code>
host=sip.sdf.org
username=$EXTENSION
secret=$PASSWORD
type=friend
context=from-trunk
insecure=port,invite
trustrpid=yes
sendrpid=yes
directmedia=no
qualify=yes
keepalive=45
nat=yes
dtmfmode=rfc2833
disallow=all
allow=ulaw
</code>
  - Go to the //Incoming// tab
  - Set //Register String// to ''$EXTENSION:$PASSWORD@sip.sdf.org''
  - Click //Submit//

You can now define Inbound and Outbound routes using this new trunk. To test inbound calls, you can queue a test call through ''maint''.

|If you have an incoming DID through SDF, just a note that the SDF's system does not pass ''FROM_DID=''.|
|If you would like to route your call through a specific incoming route by DID, then add the DID after the registration string.|
|For example: ''$EXTENSION:$PASSWORD@sip.sdf.org/$DID'' You can add the 11 or 10 digit number, just make sure it matches exactly to what you want in the incoming route.|
