Thanks for the log. This could be a bug in pjsua-lib. The PUBLISH 
framework cannot send another PUBLISH while the previous one is 
still pending, so when it gets this it will return PJSIP_EBUSY 
error. So pjsua-lib should somehow check if a PUBLISH is in progress 
before it sends another one (or probably cancels previous PUBLISH).

I've created http://www.pjsip.org/trac/ticket/411 for this.
