Call Parking - System Requirements

We are looking to enable Call Parking on a FreePBX (12) instance. Is there any guidance on the additional system resources required to support Call Parking?

We are looking to configure 8 Parking lots with each being held for up to 2 minutes. My main concern is system memory. The Freepbx is running in a VM so if it needs more memory allocated I rather do that up front before running into problems.


You told us nothing about your system how can we possible make a recommendation?

I was thinking that there might be some guidance e.g. if you have 2 calls parked for a minute you will need x amount of spare memory available. Anyway the PBX instance currently has 2GB Ram allocated and has 500Mb free.
