My PSTN line has call waiting, and I have to use zapflash application
to answer the new incoming call. If I want to flash hook to switch
calls, which channel driver do I need to look at? chan_dahdi?

I noticed that I can use hook flash to switch between SIP calls, or
even between a SIP call and a PSTN call, does this mean chan_sip has
such hook flash detection logic so I can learn from there?
