Wired handset 100 price range: supports wireless headset

[oguruma]

I am looking for a wired handset that supports a wireless headset. I currently use an Obihai202 with a wireless RJ11 handset, and that works okay, but I want to go with a dedicated wired setup for my office.

I would like to come in around $100 for the handset and another $50 or so for a decent wireless headset (external, earphone style). I run a SaaS type website and I often have to go hands-free for up to an hour at times.

I am looking for:
$100/$50 for handset/headset respectively.
Reliable with 3CX
Reliable headset/handset compatibility

You can take a look at the Yealink T42S. They support the BT40 bluetooth adapter which would then allow you to pair it with any bluetooth headset.
