What
Pockethotline is a rails app that allows you to setup a "distributed hotline". This allows you to have a hotline number that is published and operators signup with their personal numbers. When someone calls the main number the operators will be called (depending on their on-call status) and connected to the main caller.
It was originally conceived as a business by Scott Magee and Chap Ambrose at the Austin Center for Design in the winter of 2011.
The software was open-sourced January 2014.
How much does it cost to run a hotline?
Hosting Costs
The minimum hosting costs are about $35 a month. This is because a background worker dyno is required. (Assuming you're using Heroku for hosting).
Phone Costs
Twilio phone numbers cost $1/month for local numbers and $2/month for toll-free.
Twilio charges you by minutes used, $0.03/minute for local and $0.05/minute for toll-free.
Twilio's published rates are $0.01 / $0.03 but that is only for the incoming call, you also have to add another $0.02 to each call because of the outgoing connection to the operators.
Basic Setup
1. Setup accounts on:
- Twilio.com
- Heroku.com (or other rails capable host)
2. Get a phone number on Twilio
Start with the free trial number or purchase another toll-free or local number.
3. Take note of your phone number and API credentials AccountSID and AuthToken
Find them under "Account Settings"
4. Clone the repository
$ git clone git@github.com:chap/pockethotline.git
5. Edit config file at /config/initializers/hotline.rb
You must edit values for:
- config.x.hotline.name
- config.x.hotline.domain
- config.x.hotline.organizer
- config.x.hotline.organizer_email
- config.x.hotline.number
6. Save changes
$ git commit config/initializers/hotline.rb -m "updated config"
7. Create an app on heroku
$ heroku create myhotline-name
8. Enable Sendgrid add-on for sending email
$ heroku addons:add sendgrid
Any SMTP provider should work. If you don't use Sendgrid, manually update settings at config/initializers/smtp_settings.rb
9. Push application to heroku
$ git push heroku master
10. Create database tables
$ heroku run rake db:schema:load
11. Scale up worker dyno (required for background tasks)
$ heroku ps:scale worker=1
12. Add TWILIO_AUTH_TOKEN ENV variable to heroku config
Use Twilio API credentials from step 3.
$ heroku config:set TWILIO_AUTH_TOKEN=XXXXXXXXXXXXXX
13. Add SESSION_SECRET ENV variables to heroku config
First run$ heroku run rake secret
Copy the output and use it here:$ heroku config:set SESSION_SECRET=XXXXXXXXXXXXXX
14. Setup the on-call scheduler
$ heroku addons:add scheduler
$ heroku addons:open scheduler
- Click "Add Job"
- In the left-most field enter "rake oncall_scheduler"
- Change frequency to "Hourly"
- Set next run to "XX:00" (The XX will depend on the current time.)
- Click "Save"
15. Create yourself an account (edit these values)
$ heroku run rails console
$ u = User.new(
:name => 'my name',
:email => 'myemail@email.com',
:phone => '215-359-5228',
:password => 'setyourpasswordhere'
)
u.admin = true
u.on_call = true
u.save!
16. Login to your account
$ heroku open
17. Update Twilio with your app's domain
- Click on 'Numbers' in the nav bar
- Click on your phone number
- Change the 'Voice Request URL' to
https://myhotline-name.herokuapp.com/twilio/start
- Set request method to [POST]
18. Call the hotline and see if it's working!
- Don't call from the same number that you added for yourself
- If you're using your free demo Twilio account you'll hear a pre-roll message. That will go away when you upgrade your account.
- Your call should be connected after the greeting message is used.
- If calling via Gtalk fails to connect, try a real land or cell line.
19. Yeah!
Advanced Setup of Hotline Supporters
1. Create an account on Stripe.com
2. Set Stripe publishable key in config
Uncomment (remove leading '#') and edit values in /config/hotline.rb
- config.x.stripe.publishable_key
3. Add Stripe API key
$ heroku config:set STRIPE_SECRET_KEY=XXXXXXXXXXXXXX
4. Save changes and deploy
$ git commit /config/initializers/hotline.rb -m "add stripe details"
$ git push heroku
5. Visit suporters page
https://.../supporters/new
Stripe requires SSL to be enabled, if you're using your default heroku domain you will seemlessly piggy-back on the wildcard certificate at *.herokuapp.com.
If you want to use a different domain you may have to purchase and setup your own certificate.
Advanced Allow Supporters to Upload Images
1. Add your S3 bucket name to /config/hotline.rb
2. Add S3 access_key_id and secret_access_key
$ heroku config:set S3_ACCESS_KEY_ID=XXXXXXXXXXXXXX S3_SECRET_ACCESS_KEY=XXXXXXXXXXXXXX
Forward unanswered calls, change recordings, Twitter integration, etc
Look at all the options in /config/hotline.rb
