Call Waiting: ring speaker on second call

[nicknomo]

Yes, unfortunately, it doesn't seem to use the speaker, but instead uses the handset if you are using it (different than a "headset" - your other choice).

To change the tone, I went into Phone-> Tones
I selected custom

Then I put this under call waiting
0/100,500/100,0/100,500/100,0/100,500/100,0/5000,0/100,500/100,0/100,500/100,0/100,500/100,0/15000

It gives two short little pulses 5 seconds apart to let the caller know there is another call coming in. The numbers are the tone and duration. Its going 0 tone (inaudbile) for 100 ms, tone 500 ("boop") for 100ms... it does this three times, then pauses for 5 seconds, then repeats one more time, then waits 15 seconds (which means the call goes to VM).
