Connecting to FWD using IAX

It is possible to connect an Asterisk box to FreeWorldDialup using either SIP or IAX2.

This article assumes you already have a working FWD account; if you don’t, you can easily create it right on the site.

The following strings must be substituted in the examples:

• LOGIN is your FWD number

• PASS is your FWD password

• INCOMINGFWD is a context created for incoming FWD calls (you can leave it as INCOMINGFWD)

• SIP/myphone is a telephone terminal to ring on incoming FWD calls

To use IAX, you have to:

• Visit http://account.freeworlddialup.com/index_new.php?section_id=112 to activate your account for IAX

• Edit the file /etc/asterisk/iax.conf in your Asterisk box, adding: register => LOGIN:PASS@iax.fwdnet.net

in the <>General<> section (this part enables outgoing calls from you to FWD) In the same file, add by the end of the file:

[iaxfwd]
type=user
context=INCOMINGFWD
auth=rsa
inkeys=freeworlddialup

(This part enables incoming calls from FWD to you).

• In /etc/asterisk/extensions.conf, create a context for INCOMING calls, i.e. calls coming from FWD.

  [INCOMINGFWD] exten => LOGIN,1,Dial(SIP/myphone,20,tr) exten => LOGIN,2,Voicemail(33) exten => LOGIN,102,Voicemail(33)

Of course, you can dial any other telephone terminal or do whatever you want. In this case I ring a terminal for 20 seconds and then start voicemail.

*In /etc/asterisk/extensions.conf, edit your user context to allow calling FWD:

exten => _1#.,1,SetCallerId,"LOGIN"
exten => _1#.,2,Dial(IAX2/LOGIN:PASS@iax2.fwdnet.net/${EXTEN:2},60,r)
exten => _1#.,3,Congestion 

This way, when I want to dial a FWD number, I start it with 1#, like by typing 1#123456 I call FWD 123456.
