Hello, I'm used to set call-limit in sip.conf Now I switched one customer Asterisk to 16 version and can't get the behavior back, as well for extensions as for queues. I set ringinuse=no for queues and have max_audio_streams = 1 max_video_streams = 0. I wanted to add max_calls = 1 but this parameter is not accepted. Thanks for any hint -- Daniel
