Here are some best practices to avoid being blocked: Always use a valid outgoing number. Never display an invalid number in caller ID. Never substitute a phone number in caller ID to which you do not subscribe. Do not use an outgoing number that is on the Do Not Originate list. Limit the number of calls placed per minute, particularly outside of normal business hours. Limit the number of times you call numbers back within a short time frame. You should also periodically check with phone companies and third-party analytics companies about consumer complaints for the numbers you use to place calls. When leaving messages include a consistent call-back number and consider including additional contact information that recipients can use to report concerns. You can also use different outbound numbers for different purposes. For example, customer support call-backs are less likely to be blocked based on complaints if they are made using a distinct number and not one shared with outbound telemarketing calls, which may draw complaints.
