asterisk users - Mar 2007 - Answer Confirmation with SIP/AIX channels

We need incoming calls to simultaneously ring SIP phones, and a cell phone
which is called via a SIP or IAX trunk.  When the cell phone answers we'd
like a brief prompt played (e.g. "press # to accept call") and if # is
pressed
connect the incoming call to the cell phone.

ZAP trunks have some of this functionality with the call confirmation option,
but we must use SIP or IAX trunks.

Follow-me does not appear to do this since we want simultaneous ring of all 
SIP phones, and the cell phone.  Follow-me appears to ring one device for
a period of time, then the second device for a period of time, then the third
...

The answer confirmation option is required to prevent cell phone company 
messages (e.g. the phone is turned off or out of the calling area) from
accepting the call (and stop ringing on all the SIP phones).

If this is not currently possible, we are interested in offering a bounty to
make it possible.

Thanks.

I have implemented the requested call confirmaiton feature in the freepbx
followme and ringgroup applications (asterisk 1.2 for now). You can select to
have confirmation and by default any external call (e.g. cellphone) will require
such confirmation, any internal phone will not (unless you force it to) since
you usually only want confirmation when leaving the system. It is supported in
the simultaneous ring strategy (all phones ring at once).

So you may use freepbx to do this, or take a look at how to do it in the
dialplan, or contact me offline if you need something custom to your scenario.
