We have tried it all sorts of ways, and I am not big on posting phone numbers. There are web crawlers that pick up the numbers and add them to junk call lists, same thing with emails. So we choose to do it this way. Do we loose some sales, maybe. We also are able to track every lead, because when there is a reply- we have a copy. We also do not really have managers on call 24/7 to be answering phone calls on houses, so the managers can budget time each day to return calls etc.
For instance- if you called my office there is little chance you would get through to me. My admin would get your name, why your calling etc so I could be ready to talk to you.
Now if you have my cell number- odds are I answer- buy very few people have my cell number. That system, of managing my time, keeps me from being ambushed with phone calls when I am busy with other things.
Apply that same process to your managers. There are good times for them to return calls, and there are bad times. Most of my managers work full time jobs, and manage in the evenings and weekends.
So back to scale here- if your parks are big, like the ones Dave and Frank are buying with full time staff- Ring the office phone all day. They have staff there to answer calls. The reality of the parks Dave and Frank own are not in line with what I own. If they are small like mine- were we only have one full time manager, and the rest are part time- I think you need to respect the managers life outside of the park, and their job as well. If I post a phone #, people expect it to be answered. So the advise to have someone answer the phone full time is just not practical for me, therefore I need systems based on my scale of operations.
Most of the people on this forum operate smaller parks, so before you put a system into place you really need to look at the man hour cost, equipment cost etc… My advise comes from a guy that has 5 parks, in 4 states, the largest is 76 pads and the smallest is 37 pads. So I rely on systems to track what is happening, because I am just no onsite all that often. I do not have general managers, or regional managers, or lots of staff in my office.
