Hello, dear Habra community! Perhaps it was not very clear from the title of the question what I want to ask. I'll try to explain.
I am writing a spam sms filter for android. Everyone knows that spam does not come from some number (i.e. +7-123-456-78-90), but from some name (FunkyMama, Posh). The question, in fact, is whether these names are case-sensitive. For example, are POSHFRIENDS and POSHfriends physically different senders or not? It's just important for me to understand whether to consider the case when filtering or not. Otherwise, if I make the sender case-insensitive and add the user to the black list of the spam sender with the name, for example, bEELINe, then SMS from the Beeline mobile operator will also not come.
Thanks for the advice!

Register-sensitive, of course. Those. "BEELINE" and "Beeline" are two completely different source_addrs (PDF, page 59, bottom)

By the way, I thought here, probably ideally it is worth banning not the number or Alpha name of the sender, but a couple of number (alpha name) - number of the SMS center.
Since the real SMS from beeline will be sent through the Beeline sms center, and the fake one through the "left" SMS center.
PS I don’t know if it’s possible to get the sender’s SMS center in android, but in old Nokias such info was shown, which means it’s possible to get it.

For the company I use, SMS, Sms and sms are 3 different senders and each of them needs to be approved separately. But whether Android takes into account the case - I will not say.
Maybe it's worth sending 2 sms from a different sender in a different register, and then test the program on them?

A counter question, where can I get such smsgates, where can I substitute them?

why not just cast all names to the same case? In other words, how likely is it that a BeeFon SMS will be super-duper needed, and a BEEFON SMS is extremely bad for the wallet?

POSHFRIENDS and POSHfriends are physically different senders or not?

This question cannot be answered. They may be different, or they may be the same. It may also be that different senders will send SMS from one sender id.
Better make the option "case sensitive" in the filter settings

I use sip-ring.com. The only one who works number substitution.
Checked it personally. Everything is working.
