ATA device programming to send analog signal over internet

Its not a complex task. We are into security industry and work with alarms panels. Previous alarms panels only had analog telephone lines. The alarm is sent over the analog phones line. As people dont have analog phone lines they only have internet. We want to take the existing phone line and transmit it over to internet using a CISCO SPA2102 or 3102. Then the asterisk server (to be deployed) could dial out our number and transmit the same information. The service goes something like this. We just need the asterisk install and the script for provisioning spa2102 or 3102 that we could load using a webserver. Should not be more than 5-7 hours.
