I am trying to setup a T38 fax trunk. The trunk provider uses ip based authentication. The admin panel trunk doesn't verify if it is setup correctly or registerd. There is a green dot but no timestamp under registered ok. I do not have access to a fax machine to test it, but calls from a phone simply fail and do not show in the call log. Where are the more detailed system admin logs? Also, the codecs part of the trunk setup does not list the T38 codec, is this even going to work for incoming faxes?
