sipxbridge does not block the codec. at the same time the question is really a half question:
if the ATA is configured to handle t.38, you can connect a fax machine to it (and even register it to sipx if it is capable) and send a fax from the plain paper fax machine to a unified messaging fax account on sipx. At the same time, if the DID (PSTN call) points to the ATA registered device and the call is from a sip trunk provider who properly handles t.38 (i.e., it works to a unified messaging account on sipx) the fax machine will also handle the inbound fax. It also would not matter if the PSTN gateway was a POTS line or PRI, as long as the PSTN facing gateway handles t.38 properly. I cannot attest to the model you are using. We do this with Patton gateways/PRI and FXS devices and it just always works. The ATA WILL ABSOLUTLEY INTERFERE if it is not t.38 capable or configured properly. Also, since the inbound or outbound call has to negotiate a codec, the UA must support t.38. Sipx DOES NOT transcode this. It has to be natively available and offered on both ends of the call.
