I think I figured out my problem, but I'm not sure how to fix it. I pumped up SU_DEBUG to 9 and I receive line after line of su_osx_port_run: entering in the console until I my event_callback function is called the first time, then su_osx_port_run stops appearing in the console. It's almost as if the root stops running or the thread terminates.
What have done incorrectly? Thanks again. PS Sorry about the 3 postings. I was having issues with my default SMTP address in Exchange. It shouldn't happen again. > -----Original Message----- > From: Andrew Rechenberg Lists [mailto:[EMAIL PROTECTED] > Sent: Tuesday, November 18, 2008 9:21 AM > To: sofia-sip-devel@lists.sourceforge.net > Subject: [Sofia-sip-devel] Threading and timer questions WRT Sofia and iPhone > > Good day, > > I'm doing some personal research on developing for the iPhone and I've > been using Sofia to create a basic SIP UA for the iPhone. > > I have a static Sofia SIP library compiled for the iPhone simulator and > my app successfully registers with a SIP server and I can receive SIP > MESSAGEs as shown by the debugger console for the simulator.
