We're running TL v9.1.2-37 and recently upgraded to Asterisk 13.25.0-rc3. After the upgarde, we found that when adding new extensions, under Other options - Phone settings, nat and callcounter are set to "1" when they were previously set to "yes". Having it set to 1 doesn't appear to work, as we had one way transmission issues with them set this way. Changing them back to yes fixes the issue. Please look into. Thanks in advance.
