Call waiting if on internal call

[CarpeDiemTim]

I've run into a situation where call waiting only works on a T26P if you're on a call with an external line first, but not if you're on an internal call first.

In other words, if our receptionist is on a call with an outside line, call waiting works as expected. But if she's on a call to an internal extension, call waiting doesn't work, and instead, the callers just go straight to voicemail.

Any advice on why this may be?

After some research on the forum, I see that a much-requested feature is to have the phone actually ring on the second call instead of the call-waiting beep, so maybe if/when that eventually comes through, it will resolve the issue, but in the meantime, hopefully someone else has come across this and found a workaround.

Any constructive feedback would be greatly appreciated

Cheers,
