nagios phone call alerts

[PRA]

All,

I was able to configure nagios for sms and email alerts.

Now I want to make phone call alerts (using some free PBX , asterisk).

when ever a alerts is raised to nagios along with SMS,EMAIL can  I make 
it make an outbound call and play a pre-recorded message.

How can I do it using Asterisk or Is there any other simple way to do it.

Appreciate inputs.

-PRA
