I have a requirement where the call center wants to have a visual alarm, actually a red flashing light connected to a PBX station port (FXS) when the caller is declaring a site down emergency.
Looking for ideas on how to light the light for 30 seconds, while routing to call to a hotline.
First thought is using an ATA, which can function as a shared line with IP phones.
But if leaving on PBX I need to send call to DID, keep call up 30 seconds, and concurrently ring the hotlines across IP phones.
