When I call outside, there's no call waiting tone

Hmm that's odd, just tried it here and noticed the same thing on my T29. The call does show up as flashing on the second line key on the account, but unless you were looking for it/paying attention you probably would not notice as it does not generate any kind of audible beep.

Caller ID information for the inbound call can be seen by manually scrolling down, but that's not exactly intuitive either...
