I’m looking for SIP hardware suggestions that would help us send automated alerts over our asterisk phone system. I have a paging group already setup that would receive the alerts. My alert source closes a relay and plays the automated message, then releases the relay when the message is complete. I’m looking for hardware that will…
- sense a relay closure
- dial the paging group when the relay is closed
- play the audio inputed into it from the source down the sip channel
- hang up when the relay opens
does anyone know of such a device/gateway/dialer etc?
