With my previous phone (and any phone I've ever used), I could dial *70 prior to dialing a phone number to disable call waiting just for that call. I see that menus exist to turn call waiting on or off, but the beauty of using *70 is that it could be added to the number in the directory. I've been unable to make *70 to work on this phone. If I just send the number as *70xxxxxxxxxx (in the US, where I use real numbers where I've typed an 'x') the number is not accepted by my ITSP.

If I just dial *70 and send on the Yealink, my provider gives back the tone I get when the number was invalid. With any other phone, I would get back a dial tone at this point.

Anyone have any ideas how to make this work?

However, this setting seems like it is likely there to support the menu function from the phone: Call Features | Call Waiting|Disable. But the purpose of *70 is to dial it at the start of a call, and the feature will be disabled just for that phone call, without disabling it altogether. In other words, it will re-enable on the next phone call. This seems to be pretty standard among US service providers. But when I dial *70 on my phone, I immediately get a busy signal.

By the way, if I receive a call, I should also be able to dial *70 while I'm on the call to disable call waiting so the call is not interrupted by another incoming call. So, it's important that I can pass a *70 command...
