Hi all, I search google for WMI, and know that "A message-waiting indicator (MWI) in telephony is a feature that illuminates an LED on select telephones to notify a telephone user of waiting voicemail messages on most North American public telephone networks and PBXs." What does it used for in Pjsip? Is it related to "pjsua_im_typing" ? -- Khoa Pham HCMC University of Science Faculty of Information Technology -------------- next part -------------- An HTML attachment was scrubbed...
