asterisk users - Dec 2016 - Fax faling on PJSip

I am working on moving from version 11 to version 13 for my fax 
applications.
 We are bumping into an issue where the bulk of the T38 faxes are failing.

The sending test switch is reporting COMREC_ERR_TRANSMIT_PHASE
  
 These same faxes succeed on the 11 version of asterisk.
 I am wondering if there are any ideas? COMREC_ERR_TRANSMIT_PHASE
  
 Both servers are running the same version of spandsp. The dialplan code is 
the same on both.
  
 The only difference is the versions of asterisk and pjsip on the 13 
platform.
  
 Any ideas would be appreciated.
  
 Thanks

Bryant

The state machine used for T.38 and the implementation is the same
between both. There should be no problems faxing (and indeed I just
checked and the tests are passing for that). I'd suggest opening an
issue[1] and providing a trace. There may be a particular scenario where
it is falling apart.
