[Asterisk-Users] Extensions to solve three way calling problem

[PHP Mechanic]

> Have you considered setting up a meetme confrence line for them? :)

I've tried that and I get as far as flashing the pstn after a transfer: ie:
Hit the '#' and then '1' on the analogue phone.

exten => 1,1,Flash()
exten =>1,2,MeetMe,2000

 The problem is that after transfering the first caller to MeetMe I am 
unable to make an outgoing call using the pstn line, I don't get the 
dialtone and if I hang up and dial out I get a "everyone is busy" message, 
because I'm assuming that the line is still tied up with the first caller 
who is now in MeetMe.

This problem has been bugging me for weeks. It's possible to do without 
using asterisk and all the settings in zapata.conf seem to suggest it's 
possible. But I am unable to make it work. Any other suggestions welcome.
