dialplan forwarding to nortel

Im reloading a freepbx system that sits between the telco and a nortel pbx so all calls can be recorded. There are two PRIs. I need the dialplan to forward nortel extensions the the nortel system and sip extensions to softphones. I have a script that will convert the recordings to mp3s, move and sort them into folders by date preferably to an external usb drive. The converted recordings will have to be accessible and downloadable from the recordings interface of freepbx. The system is setup and running in this configuration now but barely. You should be able to copy the custom dialplan work we've already done if needed. I can have the system loaded and the sangoma A104 configured. Easy job for the right person.
