Thoughts on caller ID spoofing
Unless the telcos take measures to eliminate caller ID spoofing, this can't be used as a criteria to stop robocalls. What is to keep robocallers who use caller ID spoofing from using a different random caller ID for each placed call?
In some countries, the caller is charged for calls to cell phones instead of the recipient being charged for air time. How do these countries ensure that the appropriate caller is charged? Have these countries found a reliable method to always trace back to the originator?
