Touchmods team has released a new thirdparty software for iPhone that enables SIP calls through WIFI.

The first release was only working on iPod Touch due to a microphone problem.

The new version is working quiet properly on both platforms but is linked to one SIP provider (Free.Fr). You need to have Free.fr DSL account.

To make this software work with my asterisk box, I have made a little trick.

1) install SIPHON on your iPhone / iPod via the installer or scp
2) Modify /etc/hosts on iPhone to bypass dns resolution for freephonie.net (Free.fr pbx) and link this entry to your pbx.

/etc/hosts

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
212.217.156.112 freephonie.net (This is a fake IP!!!)

2) Preconfigure your sip account on the iPhone / iPod

/Applications/Siphone.app/accounts.xml
