Here is my config. Maybe this makes it clear for you

Yes as I said of course the sequential ephone-hunt will not ring phones that are busy.

For simplicity you can use the existing ephone-dn and numbers, if later you find out that you need different features, you can create the separate ephone-dn for hunt-group and assign to more button.

Hope this helps, please rate all useful posts!

but how to solve this so busy phones receive a second line on the second button

Scenario

Two phone for reception. One number for inbound calls.

First call goes to phone 1

Second call goes to phone 2

Third call goes to second line on phone 1

Fourth call goes to second line on phone 2

etc.

How to solve this?

If your hunt-group has two numbers in list, the third call will go to the "final" number, often voicemail. It will not go to phone 1 again.

If you want the third, etc .. call go to phone 1 again;

- configure one or more additional ephone-dn

- give it a number

- add this number to the hunt-group list

- assign this dn in overlay, or to an unused button to phone 1.

Consider however that people may have problems in handling more calls after the second one.
