[Asterisk-Users] FOP Maximum extensions?

[Douglas Garstang]

Just a curiosity really. Anyone know how I can do this?

exten => page,1,SetVar(_ALERT_INFO=ring-answer)
exten => page,2,Page(SIP/a00090101&SIP/a00090301)
exten => page,3,Playback(tt-weasels)

ie Play back the sound file after the phones receiving the page have answered? I know page is really simulating a one-way audio meetme conference, so I don't even know it it's possible.

Thanks.
