I was on the phone yesterday. I had called out using google voice voip. While on that call, I heard the noise that I usually associate with my mobile having another call coming in. I Intuitively tried to switch to it by hitting the send button on my cordless phone, but all that resulted in was a dial tone. I was able to switch back to the first call using the send button again, but by the time I got to my physical mobile phone, the caller had already left a voicemail and hung up. Is it possible to switch to such a call?
