Thanks for the reply. I have found another way of doing this as a work around. I am using now the following to put a call on hold : // disconnect the call bridge pjsua_conf_disconnect(0, pjsua_call_get_conf_port(current_call)); // silent the mic pjsua_conf_adjust_rx_level(pjsua_call_get_conf_port(current_call), 0.0f); And the following to release: // reconnect the call bridge pjsua_conf_connect(0, pjsua_call_get_conf_port(current_call)); // enable mic again pjsua_conf_adjust_rx_level(pjsua_call_get_conf_port(current_call), 1.0f); I know this is not the full-fledged legal way of achieving this but at least it did the job for me.
