Your proyect its very nice and I actually will love to use my iphone with my asterisk server, but since we can´t use it know, SKYPE does have an aplication that you can use it today with the iphone, just using SAFARI visit http://s4iphone.com an login with your skype account , they use call back system over voip, you can save a lot of money.

I'm part of a team porting the Sofia SIP stack to iPhone, we'll keep you posted on progress. We've ported Sofia to OS X before so it can't be *that* hard. We work with Freeswitch and Asterisk and are very familiar with the tech.

If anyone wants to help with the CoreAudio or UIKit parts of getting a softphone to work on the iphone then drop me a line, as that's the areas that we have least familiarity with.

I don't know if this could help but a SIP client was just released for the Nintendo DS, maybe looking for it's source code could help, here is the link http://libw11.free.fr/svsip/index.html

:-) Thanks, we already have a FOSS SIP library with Sofia: http://sofia-sip.sourceforge.net/

The build is looking good after early problems with ranlib and libtool, and I'm hoping all the test code will be up and running by Monday.

Quick! Get out a GUI so I can use it

Nice to hear that good progress is beeing made! I'm wondering though, is this a completely closed/locked solution or will I be albe to use my current SIP-server and operator?

I think it would be unfortunate if it is locked since it would force the development of a competing, truly free and customizable solution. Truphone should be able to make enough money just by making themselves the default operator and allow the users the freedom to choose. Don't you agree sleepyfox?

Well, they're using Sofia-SIP, which is LGPLed, so if nothing else they will have to release back any changes they made to get it compiling and working on the iPhone. The GUI app they build around it could be closed, however. But it shouldn't be too hard for somebody else to build an open SIP client given the working Sofia-SIP library.

Personally, I'd rather see an IAX client app on the iPhone. There are a ton of small businesses using Asterisk now, and a bunch of companies offering IAX termination. IAX is far easier to configure and traverse firewalls and real-world internet topologies with than SIP. SIP is fine for within an Intranet, but otherwise is a bit of a pain in the ass to configure.
