Can I use string interpolation in a Twilio verb?

Question

When I receive a call, I output the CallSid parameter and save it as a variable @incoming_Cid to track the call throughout it's duration and manipulate it.

When I try to bridge the call in between a customer and an employee, I dial a conference. I'd like to use the @incoming_Cid as the friendly name to make the conference unique every time.

Example:

puts params['CallSid']

@incoming_Cid = params['CallSid']

Twilio::TwiML::Response.new do |r|

r.Dial :action => '/greeting/handle-gather/techsupp/conference', :method => 'get' do |d|

d.Say 'Please wait while we connect you to one of our operators. '

d.Conference "#{incoming_Cid}"

end

end

Normally, I have the friendly name in ' ', but string interpolation requires " ". So I'm not sure if what I'm trying to do is correct/allowed?

Also, how can I output the sid params of a dialed conference like described here.

You are definitely going in the right direction here. There are a few suggestions I would make to accomplish what you are going for. Here is my modified snippet:

puts params['CallSid']

@incoming_Cid = params['CallSid']

response = Twilio::TwiML::Response.new do |r|
  r.Dial :action => '/greeting/handle-gather/techsupp/conference', :method => 'get' do |d|
    d.Say 'Please wait while we connect you to one of our operators. '
    d.Conference @incoming_Cid
  end
end
puts response.text

The changes I made are assigning your TwiML::Response to the response variable and outputting the TwiML text at the end which will be your generated XML response.

I also changed your d.Conference line to simply output @incoming_Cid without putting it in quotes, which in this case should work as valid Ruby.

Hope this helps!
