Hi,
Thanks for quick response, I have already try to use this "play_and_get_digits" command.
Its working fine when I use this as a dialplan <extension> tag in FreeSwitch file but while using it in Web Application with "<execute>" httapi command its throwing error as "[ERR] mod_httapi.c:840 Permission Denied!"
I have tried to reset Permission of "execute-apps" in httapi-conf.xml file, but still got same error.
