Hello, I’m Nathan, and I’ll be assisting you today.
Sorry to hear that you’re having trouble with this but I’ll do my best to help you out, Graham.
There are some multiline options, but they won't be line hunting, though they clearly indicate on the handset if one line is in use, so you just select the other if you need to make an outgoing call.
That system comes with 2 handsets, but you can easily add more as needed, up to 6 total.
Do you need more help with this, Graham?
