Thanks everyone for answering. I succeeded in getting the voicemail system to pick up immediately using DIL 1:1.
Until now we were using IRNA (Intercept Routing – No Answer), which has a minimum of 3 rings, so I used DIL 1:1, which doesn't have any wait time.
Thanks very much everyone, especially Carl for mentioning all the different option to use DIL 1:1, DIL 1:N and IRNA. From that I was able to see what they were set to, and I saw that IRNA was in use (with the help of the manual).
(Trying to set the "delayed answer time" was a mistake I made based on a service representative that I called.)
