Hi, When I issue a show queues command, it shows something below. 2600 has 0 calls (max unlimited) in 'leastrecent' strategy (1s holdtime), W:0, C:491, A:29, SL:100.2% within 120s Does anyone know any reference to explain the meaning of the about information? 1s holdtime: what is that holdtime stand for? W, C, A: What are they mean? BTW, does it also contain in the database if I am using ARA? Thanks.
