Using FreePBX with SDF VOIP

This tutorial shows how to add your SDF VOIP extension as a trunk in 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:

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

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.
