I kept trying adding my provider on Nagios xi so that I can receive SMS notifications.
However, since my provider is located in Europe, Serbia, in the section "Email-To-Text Address Format" %number%@ I don't know what exactly do I have to put after @. I tried a1.rs, which is the official website address of my provider, but it didn't work, I didn't receive any verification on my phone number.
I tried the same thing with another providers that I use in Serbia, but it was the same story.
At this point, I am not sure what credentials do I have to put for my provider.
Also, the phone number in %number%@, does it have to start with, for example +381 or 00381 format?
Kind regards.
Filip
