I need help with phones...?

Question

1)ok, so i have a two line on my bell phone and that means i can speak in two separate calls. & i'm just wondering if you're finished talking to someone one on line 1 .. and you're about to hang up, and the line 2 caller just suddenly calls you right when you're about to hang up(but i just hanged up anyways).. will it automatically call you back?

2) & if you're on the phone with two separate people at the same time.... (caller 1 is waiting for you, and you're talking to caller 2 ) and you told caller 2 you had to go and you accidentally hung up on caller 1.. will the phone automatically call you back or you'll just hang up on caller 1's face.??

Answer 1

(1) You have to disconnect call 1 before answering call 2. so it wont hang up, it just wont answer the call.

(2) You just hang up on caller 1.
