Hi Viki, thanks for answering. We use the sign $ to refer to our local currency, which is &quot;Peso ArgentinO&quot; (ARS); and yes, the price is that much. Importing aynthing will at least double it's original price.<br />
<br />
I'll draw a diagram of what you request and come back with it when finished. <br />
<br />
Thanks for taking the time to answer!

I have an analog door opener system in my building, this is the phone which opens the door: <a href="http://pasteboard.co/4JgctXi4x.jpg" rel="ugc">http://pasteboard.co/4JgctXi4x.jpg</a><br />
I have a raspberri pi 3 model b, and a Pcf8591 ADC/DAC converter: <a href="http://articulo.mercadolibre.com.ar/MLA-641278286-modulo-pcf8591-conversor-4-ad-da-i2c-arduino-raspberry-_JM" rel="ugc">http://articulo.mercadolibre.com.ar/MLA-641278286-modulo-pcf8591-conversor-4-ad-da-i2c-arduino-raspberry-_JM</a><br />
<br />
What I want to do, is to connect the wires that goes to the analog door opener phone system into Raspberri PI, so I can hear/speak from a sip softphone installed in the raspberry pi.<br />
<br />
Is this possible? I measured the voltage in the mic phone/speaker, it's shown in the picture. Not sure how to proceed with this.<br />
<br />
Anyone? Thank you!!

Door Opener system and Raspberry Pi

The Raspberry Pi Foundation works to put the power of digital making into the hands of people all over the world, so they are capable of understanding and shaping our increasingly digital world, able to solve the problems that matter to them, and equipped for the jobs of the future.

We provide low-cost, high-performance computers that people use to learn, solve problems and have fun. We provide outreach and education to help more people access computing and digital making. We develop free resources to help people learn about computing and how to make things with computers, and train educators who can guide other people to learn.

Raspberry Pi

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

Programming

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

Smartphones run using a variety of operating systems -- Android, iOS and Windows Mobile most commonly -- and an even wider variety of programming languages, including Objective-C, Java, Visual C#, C++ and .NET, not to mention HTML5 and JavaScript, and cross-platform frameworks such as PhoneGap.

Smartphone Programming

A smartphone or smart phone is a mobile phone with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use. They typically combine the features of a cell phone with those of other popular mobile devices, such as personal digital assistant (PDA), media player and GPS navigation unit. Most smartphones can access the Internet, have a touchscreen user interface, can run third-party apps, music players and are camera phones. Most Smartphones produced from 2012 onwards also have high-speed mobile broadband 4G LTE internet, motion sensors, and mobile payment mechanisms.

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
