Hi,
Thank you. The reason I have not to use an AGI library and also use bash shells
is because the asterisk box I'm working on, have not AGI library, there is
installed on a basic first version of Centos, and it is not an asterisk pure
box. It's from a vendor, and also have some annoyances specially with the
settings and configuration files. And I can not upgrade it, because it is
running production.
By the way, I have just get what I need.
The bash shell if anyone is interested is:
#!/usr/bin/bash
echo "EXEC \"Dial\" \"DAHDI/g2/$1\""
read line
AGI invocation:
AGI(agiFile.agi,${CALLERID(num)})
Regards,
Gustavo
