Example of using pycurl to transfer a phone number from a Twilio SubAccount to the Master Account. Couldn't get this to work with the python twilio client.

twilio_pycurl.py

import pycurl

# http://www.twilio.com/docs/api/rest/subaccounts#exchanging-numbers


def reset_demo(phone_sid):
    base = "https://api.twilio.com/2010-04-01/Accounts/"
    master_sid = "ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
    master_token = "auth token"
    subaccount = "ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
    login = "%s:%s" % (master_sid, master_token)
    data = "AccountSid=%s" % master_sid
    uri = "%s%s/IncomingPhoneNumbers/%s" % (base, subaccount,phone_sid)
    
    c = pycurl.Curl()
    c.setopt(c.URL,uri)
    c.setopt(c.USERPWD, login)
    c.setopt(c.POSTFIELDS, data)
    c.setopt(c.VERBOSE, True)
    c.perform()

phone_list = ["PNxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
              "PNxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"]

for phone in phone_list:
    reset_demo(phone)
