send voicemail with shell script

Hi, I have a shell script that sends my voicemail files as I need them to be sent. However, I cannot get that emailwav.sh file to be called. In switch.conf.xml I changed: <param name="mailer-app" value="sendmail"/> <param name="mailer-app-args" value="-t"/> To: <param name="mailer-app" value="/bin/bash /usr/share/freeswitch/scripts/emailwav.sh"/> <param name="mailer-app-args" value=""/> and restarted Freeswitch. It still tries to send with sendmail. Any suggestions would be great. Thanks. Sean
