Sending custom voice message over a PSTN line with a X100P


I’m not fully sure to be straight in-topic but here it goes.

Using a Digium Wildcard X100P, I would like to use a functionality that would dial a PSTN number and allow to post simple voice messages over the PSTN line. The voice messages would have to be in some usual digital format, like .wav or others, much in the vein of a customary linux voice modem.

Is that possible using some peculiar Asterisk functionality or please can anyone address me to a Linux sofware able to make such use of the X100P card?


Best regards
