Can I send someone money over the phone?

Can you tell me more about sending money over the phone? Is it a secure and reliable method? Are there any specific steps I need to follow to ensure the transaction goes smoothly? What are the fees associated with this type of transfer? Is it possible to send money internationally using this method? Are there any limitations or restrictions I should be aware of? I'm interested in understanding the full process and ensuring I make an informed decision before proceeding.
