TDM-->Quintum-->asterisk-->hosted phones

Hi, I have successfully setup a quintum. I was able to make call from my asterisk to quintum then passes calls from the TDM network. But Problem right now is the reverse thing. How can I configure the quintum to be able to send the calls from my asterisk(using sip protocol). Where in the quintum configuration, going to put the numbers of the hosted phone?Is it on the Line configuration and HuntLDN’s? Please help

Best Regards,
