Hello Matt,

Thank you very much for your answer and this explanation :-)

Good to know that it is already possible, good news !

However I already tried to put System() in my dial plan just after VoiceMail(), but System() never runs :

[Support]
(…)
exten => s,4,VoiceMail(1@${CONTEXT},us)
exten => s,5,System(/bin/echo test | /usr/sbin/sendmail user at mail.com)

Of course if I put System() just before VoiceMail(), it runs fine.

Am I doing something wrong ?

Thank you very much for your help !
