rails twilio api release number

Question

I use twilio gem and I do not know how to release the phone number. I try:

@client.account.incoming_phone_numbers.delete(:phone_number => phone_number)

but rails say:

undefined method `delete' for #<Twilio::REST::IncomingPhoneNumbers:0x7f35c99e93e0>

How to correct release number?

Answer 1

I found solution:

@client.account.incoming_phone_numbers.list({:phone_number => phone_number}).each do |n|
  num = @client.account.incoming_phone_numbers.get(n.sid)
  num.delete
end

Answer 2

Using the 5.x gem version and the new Twilio API's you have two options:

If you know the Number SID

client = Twilio::REST::Client.new(TWILIO_SID, TWILIO_TOKEN)
number = client.api.account.incoming_phone_numbers(PHONE_SID).fetch
number.delete

If you only know the phone number

client = Twilio::REST::Client.new(TWILIO_SID, TWILIO_TOKEN)
client.incoming_phone_numbers.list(phone_number: PHONE_NUMBER).each do |number|
  number.delete
end

Hope this helps new readers using the latest gem versions.
