Execute Call via SSH

Hi Guys,

Is it possible to execute a call via an SSH Command to call a set extention / number?
The reason im trying to do this is for monitoring of our servers, when a server goes down our monitoring system would then connect to SSH on the PBX Server and execute a command to call on call engineers / wake them up at night.

It can be a silent call however ideally if we could play a wav file that would be perfect.

Thanks
