Hi!
I have bought Miguel voice, latin , for my project. When I use it from comand line everything is fine but when I try to do the same from asterisk I get this error
[Jul 4 05:06:55] ERROR[2500]: app_swift.c:240 swift_exec: Failed to set voice.

My dialplan is this

exten => 2032,1,Answer()
exten => 2032,2,Wait,1
exten => 2032,3,Swift(Buenos Dias! Hemos instalado la voz de Cepstral. Presiona una tecla.);
exten => 2032,4,NoOp(Tecla Presionanda: ${SWIFT_DTMF}, Tenga un buen dia.)
exten => 2032,5,Swift(Presionaste ${SWIFT_DTMF}. Tenga un buen dia)
