Hopefully you can find an answer here to one of your questions. If not, please

Formatting phone numbers
------------------------
Twilio always returns phone numbers that are formatted in the `E.164 format
<http://en.wikipedia.org/wiki/E.164>`_, like this: ``+12125551234``. However
your users may enter them like this: ``(212) 555-1234``. This can lead to
problems when, for example, Twilio makes a POST request to your server with the
``From`` phone number as ``+12125551234``, but you stored the phone number in
your database as ``(212) 555-1234``, causing a database lookup to fail.
We suggest that you convert the number to E.164 format
before you store it in the database. The `phony
<https://github.com/floere/phony>`_ gem is excellent
for this purpose. Install it like this:
.. code-block:: bash
$ gem install phony
Then you can convert user input to phone numbers like this:
.. code-block:: ruby
require 'phony'
def convert_to_e164(raw_phone)
Phony.format(
raw_phone,
:format => :international,
:spaces => ''
).gsub(/\s+/, "") # Phony won't remove all spaces
end
puts convert_to_e164('212 555 1234') # prints +12125551234
