I run a business on my cell phone and it is imperative to get their number.  At times I will get a distressed person who is leaving their number and the call drops due to the fabulous coverage where we live :smileywink:
Â
How do I get a service (what is the name of such service) that tells callers that I do not accept blocked calls, therefore asking them to unblock their call before being able to reach me?
Â
Thanks!
