Short, odd, high-pitched ring-tone when I make a call - anyone else?

[Redflea]

When I make a call there is a short, odd ring-tone that occurs just after I press Dial and before the normal ringing sound begins to indicate the call is going through.

It's about 1/2 second long, can be quite loud sometimes, and is kind of high-pitched....sorry, it's hard to describe. The tone modulates up and down quite fast - da-dum-da-dum-dum (if you can imagine).

I tried re-programming the phone, and also updating roaming, and it's still there every time I make a call. I haven't made any changes to call settings to speak of...never had this on my D1.

Appreciate any info -

Thanks!

Never mind...

Settings>Sound>Call Connect

I had enabled that, thinking it would make a sound when I dialed someone, when the other person picks up...instead it makes that tone right after you hit the dial button.

No idea what it is used for, but useless/annoying for me. Turned it off.

Let's you know the call connected to the network....
