I have a running VoiceXML application that works ok in Nexmo. If I set any language other than en-US the calls want get answered. I just change en xml:lang as in:
<vxml application="/dialogue/root/50b9bab0-9ce8-4d7a-9389-09f06aa8f9ee" version="2.1" xml:lang="es-es">
I have tried in the vxml above and also in the prompt tag. Any language like es-es, es-ES... even en-UK will make my vxml stop working in Nexmo. I am sure script is OK as I can change en-US female and male voice with en-us-male and en-us-female. That works.
Am I missing something?
(I don't think it makes a difference but I use the great Rivr java library to generated vxml)
