[asterisk-users] How to do a 3 party Warm Transfer in Asteriks 1.4

[Miguel Molina]

> We are running Asterisk 1.4 and need some help to determine how (if)  * supports 3 party warm transfers.  I've searched quite a bit  and all I can find is information on "attended transfers".  What we are looking for is: (1) external inbound call A comes to * extension B, caller A is placed on hold and extension B calls external third party C.  After explaining caller A issue to Party C, *Ext B brings Caller A onto the call and introduces A to C.  After the into,* ext B then drops off the call while A & C continue the call.  Any help would be appreciated.

The built-in attended transfer asterisk has, works OK and won't drop the 
entire call when B hangs up to complete the attended transfer (with the 
* key). On the asterisk attended transfer, B calls C to explain the A 
issue (while A waits with MoH) and then hangs up (with the * key) to 
complete the attended transfer leaving A and C connected, but the part 
where you want all three talking do to the "warm" introduction cannot be 
done, unless you use a Meetme conference to put all of them on the same 
conversation.

There may be some applications that do this without the need of a Meetme 
conference, maybe someone else can enlighten us.

Cheers,
