It looks like I need to interface my asterisk system with some FXO ports for faxing. I can’t tell which is better though, the digium or the sangoma product? As with all hardware I know there is a lot of debate. I see that the Sangoma product has a hardware timer that can link to another PRI card for timing purposes. But are they as well supported as the Digium cards? A little advice, or a lot of discussion would be awesome.
