Blocking calls on iphone

Yesterday I received a call from a number in Florida 001954 5945084. I ignored it and a message went to my voicemail.

I used the block feature on my phone.

This evening I notice that a new message has arrived in my mailbox and it is from the blocked (spam) number - I recognised the voice.
. No number appeared on my phone prior to this because I had blocked the number yesterday?

How can I prevent blocked numbers accessing my mailbox?
