I have to connect an anolg pbx to a remote asterisk,
i thought to connect the pbx to the fxo port of an ata device and the 
ata to asterisk throught the wan.
Calls arriving to the pbx can be forwrded to sip phone connected to 
asterisk.
If the called part wants to transfer the call to an extension of the pbx 
he have to send an hook-flash throuth the ata's fxo port.
Now i guess: is an ata the rigth device to solve this problem (is there 
an ata that can send an hook-flash to fxo port from sip) or i really need
a local asterisk with an fxo card that connect to the remote asetrisk?

Any help or suggestion is welcome
Thank's
