Voicemail cannot be accessed in spanish

Binary package hint: asterisk-prompt-es

I've discovered an error related to the afternoon.gsm file on the asterisk-prompt-es package. This file is used when accessing the voicemail and since asterisk doesn't find it, the call is ended without letting the user access its messages. This is the output of the asterisk shell:

I've discovered that the file isn't inside the digit directory but in the root of the sound files, for both the English version and the Spanish version. I've checked the error using the English voice files, and it doesn't happen, so it must be a problem related to the spanish voice files package.

The afternoon.gsm file should be moved or linked in the digits/ folder.

Apart from this, the voice files used in this package are no longer supported by its source:

So I think that the new voices should be added if not for gutsy, for the next Ubuntu release. The new voices, with CC license, are available at:
