Hi All; I am face to face with weird problem. When ever i call application destroy it stucks at pjsua_call_hangup_all at the line when pjsua locks.. than it keeps looping inside the pooling. WirofonApp.ocx!pjsua_call_hangup_all() Line 2106 C WirofonApp.ocx!pjsua_destroy() Line 1253 C any idea why that might be happening?
