Hunt group question

I’m replacing a telco system with a freepbx box. The telco currently has a hunt group setup for 2 numbers as follows (numbers replaced for privacy):

line A: 555-1212
line B: 555-1122

Now, if I call line A, it will ring for a while and then if nobody answers it will go to line A’s voicemail. If line A is busy, then line B will ring for a while and then if nobody answers it will go to line A’s voicemail. Likewise, if I call line B, it will ring for a while and then if nobody answers it will go to line B’s voicemail. If line B is busy, then line A will ring for a while and then if nobody answers it will go to line B’s voicemail.

my issue here is that i’m not quite sure how to set this up. I tried to set the busy destination for line A to line B, and vice-versa, but if both lines are busy, the caller gets the message ‘I’m sorry, an error has occured with call forwarding’ and then the call drops.

In the console/logs I see the call get bounced back and forth between the two extensions, then finally dumps out this:

I’d considered using a ring group instead, but it seems like that wouldn’t work well, as I wouldn’t be able to know where in the list I am (i.e. calls to line B would start with line A), and I don’t think setting up a separate ring group for each DID would be very scalable.

For references, these lines are backup lines within the same department.

I’m using pbx distro, version 3.211.63-5.
