Hi. I'm unable to join/left (log in/out) a queue with this procedure (keypad or BLF): https://help.yeastar.com/en/cloudpbx/topic/log_in_out_a_queue.html
For example, if i digit 6400* or *756400, where 6400 is a queue where i'm a dynamic agent, PBX hangs up.
My PBX is a Yeastar P-560 with last firmware.
How can i do?
