Not in any way a good solution, but what I've done is create an extension that flashs the line, and then returns the call to my sip phone. For example:
[app-flash]
exten => _*4.,1,macro(test,${EXTEN:2},${CALLERIDNUM})
[macro-test]
exten => s,1,Answer
exten => s,3,Flash
exten => s,3,Dial(SIP/${ARG2},30,t)
exten => s,4,Dial(SIP/${ARG1},30,t)
exten => s,t,Hangup
exten => s,i,Hangup
exten => s,h,Hangup
Then if you're on a call through the Zap line, and transfer the call to *4xxxx, it will flash the line and return it to xxxx SIP extension. I've been trying to get it to auto-detect the SIP extension to return it to, but callerid is different depending on if the call is incoming or outgoing through the Zap.
Again, not good.. but works in a home environment. I think we'll need in-call triggers to do anything better.

Subject: [Asterisk-Users] call waiting, * and FXO
> I have been told that the combination of call waiting, * and FXO does and will not work because “Asterisk is a PBX”. I guess I’d like to hear if this is a hard and fast “no this will not work and here’s why”, or that this currently doesn’t work but with some coding might work.
