Colleagues, please tell me how to apply the changed log level value? I read the API documentation, in particular the "Group PJ_LOG" chapter. I wrote a test code in full compliance with its content. It is launched by the command interpreter, after PJSUA initialization. *int v, n;* *n = atoi (arg); v = pj_log_get_level (); printf ("\nbefore %d, new %d\n", v, n); pj_log_set_level (n); v = pj_log_get_level (); printf ("\nafter %d\nj", v); *Apparently, the functions work fine, the new value of level is returned on the second request. * However, this has no effect on the actual verbosity of the application. It remains the original. * I suppose that something else needs to be done for the new value to be applied. Unfortunately, this is not in the documentation. *What am I forgetting to do?* -- Thank you in advance for answers to the essence of my topic, Ogogon.
