Re: when i call someone on my n900 and this person i'm trying to call is waiting with someone my n900 don't tell me that the call is waiting !!! why ???
 

let me get this straight. when you are talking to someone on your phone, and someone else calls you, you phone is not showing that you have incoming call?

no no no i mean that (when you are trying to call someone and this person is on a call with another one your mobile tell you that this person is in a call waiting with someone) the call waiting is working good but this is not working :( :(

Yes, you do - Inbound call waiting works fine, when you get an incoming call the phone speaker beeps, and you get a little image for the waiting call in the top left of the screen (below the status area) which lets you switch between calls by pressing it.

The OP's query is about outgoing calls to someone else with call waiting enabled though, which is not something i've tested. I'm unsure exactly why the OP needs any kind of notification on the display that the call's waiting (on hold) rather than ringing or being answered though, surely you can hear that perfectly well.

my n900 does this. If i call somebody who is already on another call, my phone flashes a "call waiting" message on the screen and continues to ring until they either answer or it goes to voicemail. maybe its a network thing but this deffinatly works on my n900

Is there a phone that does this? If so, which one?

can you tell us what is your service provider and where are you located

Re: when i call someone on my n900 and this person i'm trying to call is waiting with someone my n900 don't tell me that the call is waiting !!! why ???
 

What's the significance of this behaviour?

Shouldn't you be able to tell by listening to the different tone? (And that's more practical, since you don't have to look at the supposed screen message)

Place your SIM in another of your N series phones and ckeck that call waiting is setup on that phone. As it is a network setting when you transfer the SIM back to your N900 the setting should remain.
