We have clients that are use to having a flash button programmed on their phones. They use the flash button for warm transfers such that when a caller calls in they can hit the flash button > get a second dial tone > dial the 3 party > hit the flash button again > then hang up the phone with the other two parties still being connected.
We are looking to upgrade them to a UC540. We have SPA525G phones. I pretty much figured we are not able to add a flash button through the CCA. From reading the forums, it looks like the only time a flash button appears is through a soft key while you are on a line and another call comes through to that phone. However, this will only work in the case if we want call waiting, but we are looking to get a warm transfer going like describe above. Anyone have a way of programming a flash button or the same capability on a button or know the CLI command to do so?
