Asterisk phone/e-mail interaction

Hello all,
I’m signed up to a couple e-mail lists that send messages in a very specific format. These messages are usually time sensitive.

I know how to set-up fetchmail to automatically pull in POP e-mail.

Is there an easy way in Asterisk to ring the extensions? I can set-up pop, and make it trigger a script if one of the desired e-mails is received… what could the script invoke to ring the phones? Beyond that, an enhancement would be to have a prerecorded message play when the extension is answered.

Possible? Anyone have suggestions on the best way to acoomplish this?
