Hello,

I'm trying to get past a problem I'm having with Auto Attendant on a XN120, this is the first time I've used the AA feature on this system.

The goal:
When 1 is pressed from the menu it will ring 3 extensions at the same time.

What I've done:
Setup the Analogue trunks to go to VRS and recorded message 01.
Added extensions 601, 602, 603 to department group 1 - "Extension Group All Ring Mode Operation" set to Automatic.
Add pilot number to Department Group 01 (301)
Set DISA One Digit Code received digit 1 to destination 301 (department group 01)

The problem:
Auto Attendant works fine, but when 1 is pressed it rings 601 then 602 then 603 instead of ringing all three extensions at the same time.
However if I manually dial 301 from one of the other extensions, all three phone do ring at the same time and no hunting is present.

For some reason the AA seems to behave different to internally dialing the Department Group.

I'm sure it's something easy I'm missing, but a bit stuck at the moment.

Any help is appreciated!

Thanks.
