asterisk users - May 2005 - AGI - How to Make Calls and Bridge to Original Incoming

I need to accept an incoming call, make a series of outgoing calls, and 
once I find someone willing to accept the call, bridge the original 
incoming call to the outgoing call.

Using Dial from an AGI script isn't enough because once the Dial'ed 
number connects, the call is immediately bridged and I need to ask the 
called party if they will accept the call.

I can see a couple of possibilities but I know the Asterisk gurus on 
this list can think of a better approach.

(1) Throw the incoming caller into a conference, make the outgoing calls 
using outgoing directory until we get a winner, throw the willing called 
party into the same conference.

(2) Park the incoming call, make the outgoing calls, transfer the 
willing called party to the parked call extension (not sure this will 
work but?)?

What is the quality solution?

Thank you so much!

I was not familiar with this option since we only run STABLE and this 
feature is only available from CVS. Since we cannot risk running our 
main switch on CVS what I have done is set up a second server in the 
rack running the current CVS version, IAX calls from our production 
server to this box which avails itself of this new Dial macro feature, 
uses IAX to link back to the production server to make the outbound 
calls, and then bridges the call once an outbound call has been accepted.

Thanks again for your suggestion. Now to wait for Dial with Macros to 
make it to stable :-)
