hold-the-line - Simple Python voicemail and SMS/MMS receiver for holding onto phone numbers in Twilio

Verifies Twilio security signatures at all times; this may make local testing difficult without additional changes.

Runs through AWS Lambda via Zappa, see past commits for gevent/systemd/init.d/etc. versions.

$ ~/Library/Python/2.7/bin/virtualenv env
$ source env/bin/activate
(env) $ pip install 'twilio<6.0' zappa phonenumbers marrow.mailer flask
(env) $ zappa init

Then edit your zappa_settings.json to reflect your usage, e.g. if this is one of many hold-the-line instances, changing the name of the deployed project:

{
    "dev": {
        "app_function": "holdtheline.app", 
        "aws_region": "us-east-2", 
        "profile_name": "zappa", 
        "s3_bucket": "zappa-██████████",
        "keep_warm": false,
        "project_name": "holdtheline-██████████"
    }
}

keep_warm is also set to false because Twilio will wait up to 15s for a response, and even on a cold start, Lambda will generally return in that time or less.

I deploy two different instances from the same source, so to deploy I then do:

(env) $ cp holdtheline.██████████.cfg holdtheline.cfg
(env) $ zappa deploy dev -s zappa_settings.██████████.json
