If your IVR solution returns an error, such as "We’re sorry, an application error has occurred – Goodbye". This may be due to characters in your settings that cause the XML parser to fail.
MetaLocator support staff can look up the exact issue in the logs, but it's commonly due to accented or special characters in the settings. These can be replaced by their HTML entity equivalents to avoid this issue.
So instead of
Lo siento, no entendí su solicitud.
Use
Lo siento, no entendí su solicitud.
