Iridium Modem as Trunk

Hello All,

I have a new project to integrate an Iridium modem to Asterisk. The Iridium modem has two voice channels. I intend to connect the modem to the same hardware that is running Asterisk.

How do I allow my Asterisk users to make/receive phone calls over Iridium voice channels?

Has anyone done this? Can you please point the direction for me?

Thank you,
