Next, configure your IAX2 softphone to register to Asterisk. If the phone successfully
registers, you’ll see something like:

*CLI> -- Registered IAX2 '1001' (UNAUTHENTICATED) at 192.168.1.104:4569

Configuring the Dialplan
In order to allow calling between our two Asterisk boxes over the IAX2 trunk, we need
to configure a simple dialplan. The following dialplan will send all extensions in the
1000 range (1000–1999) to Osaka, and all extensions in the 2000 range (2000–2999)
to Toronto. Our example is going to assume that you have configured a pair of IAX2
softphones, but feel free to utilize a SIP phone if you’ve already configured one (or two).
Just be aware that you’ll need to change the Dial() application to send the call to the
SIP phone via the SIP protocol instead of IAX2 (i.e. Dial(SIP/${EXTEN},30) instead of
Dial(IAX2/${EXTEN},30)).
