I am working on a security camera system as a favour for some people I know. One aspect of the system is that, once movement is detected, a phone number is called (I am not trying to spam call anyone :-)
I need to know a way to automatically dial a phone number.
The computer running the system runs linux, and has internet access, but does NOT have physical access to a phone jack so I cannot use a local modem. Either it must have some agent on the local area network do the dialing, or use the internet in some way.
I looked into using the Skype API, but that was a massive mess and people are no longer allowed to access the developer site as it's supposedly being revamped.
The other solution I am investigating is having a network-connected microcontroller talk to a serial modem, but this seems awfully complicated for something that should be so easy.
Any suggestions would be greatly appreciated, thank you.
