[Asterisk-Users] threeway calling not working

[PHP Mechanic]

Hello,

I'm having a few problems with getting zapatta.conf to work properly:
threeway calling is enabled by my telco and works when not connected to 
asterisk. The problem is that threeway calling doesn't work nor does call 
forwarding. With threeway calling I am unable to send a hook/flash to 
asterisk and when I try call forwarding I can set it but  the call does not 
get forwarded I get a everyone is busy message and then the call gets 
directed to voicemail.
