The cost of the boards vs the cost of an external Ethernet gateway are negligible, however, with the gateways you get hardware codecs and if the server crashes you can have the hardware gateways immediate send calls over to the secondary server.
As for USB, I don’t know of anything USB that really works for FXO and FXS.
Companies like Adtran TA900 series and Sangoma Vega series seem to be very reliable, the later can be a little bit of a pain to configure

Hey Ken, why the recommendation to use an external gateway instead of FreeTDM / Sangoma / Dahdi-compatible boards?

What types of FXO and FXS devices does FreeSWITCH use?
Thank you
