After working on the Asterisk iPhone port this weekend, I decided to try something a bit more complex and port the Sofia-SIP library to the iPhone.  I had it working on my Nokia N770 tablet as a CLI SIP client and while it wasn’t pretty, it was a functional SIP phone.  There are two key parts to getting this working on the iPhone:

1. Port the Sofia-SIP core libraries, which is now complete (binaries are here)
2. Port the simple cli client sofsip-cli.  I’m in the progress of doing this now and hope to have something working soon.  If everything goes as planned, I should have a working cli sip client on my iPhone.  I’m not sure about the audio in/out, but I’ll cross that bridge when I get to it.

I’ll keep updating as I progress, but so far things are looking good.
