T38 Passthrough and Fax Extensions


I am using FreePBX 1.1005.210.62-1 and a SIP trunk provider that supports t.38 faxing.

Is it possible to have both an ATA type extension like the SPA112 or Grandstream HT502 with t38 passthrough on, and still have SIP detect inbound routes to fax exensions at the same time?

Yes fax detection (nvfax or Digium) is just an inline artifact used to route the fax calls (or not)
