I have a client that has one 3CX instance but 12 different sites (restaurants). They would like to have each restaurant have 2 park lines that only their site can use configured as BLF buttons. When I try to configure their extensions, I only have 10 Shared Parking slots so this won't work. I am trying to wrap my brain around how we have 50 slots according to the documentation (https://www.3cx.com/blog/docs/call-parking/) but only 10 in the BLF setup... My brain hurts. Can anyone help educate me? Thanks!
