Is there a shortcut for blocking spam calls?

Hello there, I’m using iPhone 11 since last 1 year.

As we know recently spam calls increased day by day. I’m also receiving such type of spam calls on my phone and to prevent those calls I also used call blocking app but that’s not much useful Because spammers calling from different different numbers with the same series code.

Now I’ve an idea to reject them automatically via shortcuts and scripts feature of iPhone but I don’t know how to create such type of script 😌

I want create script which blocks all the received calls from series “+91 172” I’m going to attach screenshot also that how spammers calling me via different different numbers but the series is same +91 172

it would be very helpful me to create such type of shortcut, thanks!!
