Background

Our Hack: Domokom – your intercom via mobile!

Hubert & Dominik – we work @Pro_IDS

One day in the office we had the idea to answer the centrally placed (and far away - yes sometimes we are lazy) intercom on our mobiles…

We worked on the hack after hours and here is the result…

Basic Use Case

Guest “rings” the intercom at the door

Domokom intercepts ringing and calls the home owner’s mobile

Home owner answers the call and talks with guest

Owner can also open the door using mobile

Domokom

Domokom Box is a dedicated hardware add-on to standard intercom

How it works?1. Raspberry Pi

intercepts the call

2. Raspberry dials RestComm

3. RestComm calls registered SIP client

4. Voice call established between SIP client and Raspberry

5. Entered DTMF code opens door

Advanced Use Cases

Parallel ringing Several mobiles called

simultaneously – call established with first answering user

Sequential ringingSeveral mobiles called one after

another

Time dependent call routingExternal application allowing to

define call recipient schedule

Welcome messageCustom greeting recorded by

owner & played back to guest

Voice Mail - guest records a message delivered to ownerIn case nobody answers the call an

announcement is played and the guest can record a message which will be sent via e.g. e-mail to Domokom owner


How did help?

Handling SIP calls – SIP registrar, SIP signaling Media server:

establishing voice calls recording voice prompts

Fast & easy development of application logic for multiple scenarios –using Restcomm Visual Designer

Text-to-speech – playing announcements Implement more complex scenarios as external applications (Scheduler) Easy deployment & administration in the cloud Possibility of interaction with legacy devices – e.g. plain phone calls Virtually unlimited extension possibilities – new use cases on the way…


Future Extensions

In the future we see the following extensions to Domokom:

Dedicated mobile app – replace the Linphone SIP client with an app that allows the user to manage her account and handle calls

Notifications Notifications via various channels (e.g. SMS, MMS, IM) about Domkom

events such as: guest ringing, door opened, etc.

Video call handling – adding video calling capabilities

Connect Domokom box to WiFi AP instead of cable connection

Ultimately, replace Raspberry Pi with smaller dedicated hardware
