Quicker switching from internet to phone audio in RCV (Glip)

When attending a meeting from a laptop, I sometimes need to switch quickly to phone audio due to call quality issues. When I use the 'Call Me' feature, after connecting, it requires me to dial 1, but then still tells me how many participants there are before actually connecting me. Switching this connection takes over 25 seconds, which is a long time when folks are waiting to hear me speak. I would like to be able to press '1' and have it connect very quickly.
