Alert systems

Until now, only the traditional alarms systems could be used to send alerts to the Central Station. (Central Station is a common term used to refer to a company that provides services to monitor burglar, fire and residential alarm systems.) However, due to Ozeki VoIP SIP SDK, you can now communicate with the Central Station over VoIP by using your own C#.NET application.

It means that Ozeki VoIP SIP SDK allows you to receive Contact ID alerts coming from your alert system when there is an alarm in case of emergency. This way, we could say that 'you can be the Central Station'. You can be the other side as well: you can send out any alarm as if that would been sent by an alarm system. All this is possible with your C# application through your VoIP network.
