We are continuing to evolve Tropo, by releasing a new upgrade to the Tropo cloud. This upgrade includes the following:

• Support for fetching Java Speech Grammar Format (JSGF) and Speech Recognition Grammar Specification (SRGS) files from an external HTTP or FTP server, in addition to the built in support for Simple Grammar. We are working on a couple of follow up posts for how-tos on using these enhanced speech grammar capabilities.
• When placing an outbound call, you must now include the ‘+’ and country code. To dial in the US would then need to be ‘+1415551212′ for every outbound call.
• The ‘#’ symbol on the telephone keypad may now be used to terminate a recording in a Tropo application.
• Addition of MP3 as an audio file playback format.
• You may now play touch-tones (DTMF) after a call has connected. You may now issue a call with these additional parameters: “+14155551212;postd=1234;pause=22000ms”. Where ‘postd’ is the digits to be dialed and ‘pause’ is the amount of time to wait after connecting the call to issue the digits.
• New accounts will now need to request outbound dialing access from support@voxeo.com. All existing accounts have outbound enabled and will continue to do so.

We continue to work on many new features and will roll them out as they become available. Enjoy the new features!
