BLF re-park

[jolouis]

Still sounds like a strange route to take. Usually you have:
1 x Park Button
1-4 x Parking slot buttons.

So you take the call, and hit Park Button to park it. Asterisk sticks it into one of the slots and you see the BLF for that slot change. Then to pick the call back up, you press that BLF or dial the parking slot number.

I can confirm in this configuration things work normally and you can park/repark as many times as you want without disconnects.

I'm not sure how you have your single BLF/park button setup as I could not get a single button to act as both a park and a pickup/blf at the same time... maybe your Asterisk dialplan is different in some way though.
