Thanks Benny,

I think no. No calls to on_call_state nor on_call_media_state nor 
on_incomming_call sucess.

Who? Not me.

mmm no, actually do nothing, no threads, no mutex.

My port do not use sound card, but could be, how can initialize the library 
with --null-audio ?(Do pjsua parse itself argv?)

thanks Benny!

Cheers
