Hi. Manjeet, thanks for your reply. Unfortunately I still have problems with that. Maybe I?ll write what I have and what I want to have: My driver ( DLL) is based on external library. In one method of its class, let say: Line::MakeCall() I want to call pjsip function to handle SIP communication. This function is simply PJSUA example with little changes from: http://www.pjsip.org/pjsip/docs/html/page_pjsip_sample_simple_pjsuaua_c.htm Currently I have this PJSUA example as method of my another class, let say SipComm::initial(). As I see this code has some threads because without my changes I was receiving: "Calling pjlib from unknown/external thread. You must register external threads with pj_thread_register() before calling any pjlib functions." Thus I wanted to register and create thread ( e.g. pj_thread_create with SipComm::initial() as parameter) and different combinations with calling it in SipComm::initial() or in Line::MakeCall() before invoking SipComm::initial() but I receive only "Calling pjlib from unknown/external thread.." or hang out of driver. I know that this description may be not satisfactory and so I would have bigger thanks for any advices, because currently I?m out of ideas.
