i also get the same message when running ztcfg -vvv after the upgrade.  
However i would assume that a small patch to ztcfg.c to print  
something else in the below if statement should take care of this,  
since it doesn't seem to be an error per se. When running ztcfg -vvv  
it actually correctly identifies Channel 16 as MTP2.  Please note am  
not a coder and i might be wrong.

  if (needupdate && ioctl(fd, ZT_CHANCONFIG, &cc[x])) {
"ZT_CHANCONFIG failed on channel %d: %s (%d)\n", x, strerror(errno),  
                                                 if (errno == EINVAL) {
fprintf(stderr, "Did you forget that FXS interfaces are configured  
with FXO signalling\n"
that FXO interfaces use FXS signalling?\n");
