Hi Brian,

You'll have to use 1.6.17 if you ever want any faxing to work in all test cases.

Hello,

I am using opensips as entry point using dispatcher. opensips( 127.0.0.1), i am routing call to freeswitch server (127.0.0.3).

Now I am trying to receive fax, my issue is when i try to send fax in softphone(Zoiper) from the log i am seeing that it is sending fax using t30 codec. and i am not receiving the fax at destination, is it because of codec, should it only work with t38 codec? if that is the issue than how am i be able to send the fax using t38 from zoiper?

Here i am attaching the fs log with loglevel 9 and sip trace is also enabled.

127.0.0.2  => carrier/provider IP
123456789 => Fax number
test@gamil.com => Email Address
127.0.0.4 =>UI IP
