First, my browser crashes when I try registering a thread Just to be more precise, you need to register the current thread before calling PJSIP/PJLIB API, *only* when the current thread has not been registered to PJLIB before *and* this thread was created using native thread API rather than pj_thread_create(). > before using pjsua_create,pjsua_init or pjsua_start.

In other words, no need to register the thread that calls pjsua_create() since this will have been done in pj_create(). > self-generated thread).

A slightly better approach probably is to check whether the thread has been registered before registering it again, using pj_thread_is_registered(). But there is a bug in your code. When registering a thread, the pj_thread_desc MUST have a lifetime that's at least the same as the thread being registered (or the easiest is to make the pj_thread_desc variable static). So you cannot allocate this from a local variable like the one in your code. cheers, -benny > I usually call pjsua_destroy (to free resourses and de-register).
