I am trying to have an inbound call ring extensions 301, 302, & 303 at the same time. If after 15 seconds no one picks up I then want it to hunt style ring extensions 304 & 305. If no one picks up after 30 seconds I want it to go to an IVR.
My thought was to make a ring group, 601, that will ring ext 301, 302, & 303 at the same time and a separate ring group, 602, that would ring ext 304 & 305 hunt style. Then create a 3rd ring group that the inbound call is directed to that would list ring groups 601 then 602 as extensions and use a hunt style ring strategy. However, it appears that I can’t use ring groups as extensions in other ring groups. When I do so I get sent to the destination if no answer for the inbound ring group.
Is there another way to accomplish this?
