Title: T.38 on OBi200: What are "FAX Event" and "Telephone Event"?
Post by: SeanTek on August 11, 2017, 10:27:49 AM
I am trying to set up T.38 on the OBi200. What are "FAX Event" and "Telephone Event"? These have Codec parameters "fax-event" and "telephone-event", respectively:

FAX Event

Telephone Event

In particular, FAX Event is disabled by default. http://support.t38fax.com/support/solutions/articles/19000012047-obihai-obi200 says to enable it, but it's not clear what actually this does, and what the consequences are of having it on or off. (Apparently, the OBi200 works just fine with G.711 fax pass-through without FAX Event enabled.)
