Hello and thanks for reporting this,

I suspect that there is something wrong with iaxc_set_formats() function call 
which is implemented in libiaxclient and declared as:
iaxclient.h:EXPORT void iaxc_set_formats(int preferred, int allowed);

Could you please perform the following test: apt-get source kiax and find the 
following method implementation in src/iaxwrapper.cpp:

bool IaxWrapper::init_iax_client()
{
  int result = iaxc_initialize(AUDIO_INTERNAL,getSettings()->getMaxCalls());
  debug( "IaxWrapper::iaxc_initialize() result = %d\n", result);
  if (result==-1)
  {
    // hopefully not many people will have to read this..
    fatal_error("cannot initialize iaxclient!\n");
    return false;
  }
  iaxc_set_formats(IAXC_FORMAT_GSM,IAXC_FORMAT_GSM|IAXC_FORMAT_SPEEX|
IAXC_FORMAT_ULAW|IAXC_FORMAT_ILBC);
  return true;
}

Since result is said to be 0 (from your log above) it crashes in 
iaxc_set_formats(). So call it this ways instead: 

iaxc_set_formats(IAXC_FORMAT_GSM,IAXC_FORMAT_SPEEX);

Recompile kiax and try again.
