Has anyone ever implemented an automated announcement and/or emergency notification tool that either integrated into CallManager directly or via H.323/SIP/POTS that has the ability to record a greeting and schedule to call outbound to the PSTN to play the greetings. The PSTN destinations would be retrievable via flat file or database.
The solution doesn't need to be too big as there are only about 300 PSTN numbers required to be reached.
We have found hosted solutions are way too much for our taste (~$60k).
I would appreciate any company suggestions that could provide this tool for our needs.
