Hi Ateneahost,
The dialplan sample that demonstrate Integration Server payment gateway functionality is bundled with Visual Dialplan and comes with English voice promptos. There are three voice prompts used in this dialplan: EnterCardNumber.gsm, EnterExpMonth.gsm, and EnterExpYear.
We do not have these prompts recorded in Spanish.
However, all you need to do is to record it in Spanish, in GSM file format, and upload it to /var/lib/asterisk/sounds folder.
Best regards,
Daniel Minitch
