I accidentally called someone, will they get it?

I accidentally called my ex (from my iphone to some android type phone) in the process of deleting him! I didn't hear any ringing, and I think the thing was still displaying "calling __…" before i hung up. The call lasted barely a second… Please tell me the call didn't go through, if it did then i'd die.

If you know someone with the same type of phone he has then perform the same call (the duration) and hang up and see if it goes through.

(When I say "same type of phone", really I mean same phone carrier. The same actual phone type will help.)
