Hi. I have been searching through old threads and various forums, but can't seem to find out what the consensus view is here on the best type of FXO hardware to use for a home asterisk implementation. Specifically, should I buy a FXO ATA like the Sipura 3000, or a PCI form factor port like the Digium TDM400 series. I have read horrible things about problems with the X100P, so I have ruled that out. The Sipura 3000 gives me the ability to get an FXO/FXS configuration that I can put anywhere in the network, which simplifies my wiring a bit (I'd rather push 100BT signals around than analog telephony), but I don't know how reliable it is in an FXO role compared to the TDM400. Am I missing another FXO hardware option that is even better? Also, does it matter if I am trying to use faxdetect on any of these ports in terms of which is a better interface? Sorry if there is an obvious answer to these questions. I'm just trying to get my feet wet with Asterisk for the first time. Thanks, Mike --------------------------------- Do you Yahoo!?

If you use the Sipura 3000 (which is nice, by the way) Asterisk doesn't actually answer the call, but the Sipura does and passes it over SIP. It may cause issues with hanging up. Sometimes mine stay off-hook and I have to reset them. Specifically, should I buy a FXO ATA like the Sipura 3000, or a PCI form factor port like the Digium TDM400 series.
