My company is looking to convert our multisite customers away from their current phone systems and move to 3CX. The users are accustomed to shared parking rooms with BLF to indicate if a caller resides. Our usual configuration would be 2-4 shared parks per office building across 25-30 buildings. The only limitation restricting us from running all of a customer's users off one system is this shared parking room limit of 50. Please consider increasing this to support large multisite companies who wish to maintain the same functionality as they migrate from other VoIP platforms. I recommend 150 as that would support the largest of my multisite customers.
