Twilio ios客户端应用程序将参数传递给服务器，以便将新成员添加到会议中

Question

I understand that Twilio conference call is a way for multiple people to connect to the same session.

Once in a connected conference call where there is an agent, and multiple clients through a iOS app as a Twilio client connected with a capability token they want to add more people.

Let's say that in 14:00h, agent and client1 have connected to a conference call friendly_named Conference1.

While in this conference, client1 with his iOS app, presses the + button to add a new client (client2). Then selects from a list of phone number [phone], or types the phone number [phone] and the person with phone number [phone] is connected to the conference call by my server.

I know how to add a new person to a conference call, that is I have made the server PHP code to connect a phone number and add him to the conference call.

$client->account->calls->create("twilio number", [phone], ...)

But how can an iOS client app pass this parameters (phoneNumber, friendlyConfName) while in a call with an agent, to my server so I can handle it (that is call the client2)?

I can maybe have a route/addMember where the iOS client passes the number/s.

I'm asking about the iOS applications side: how can the iOS pass parameters to my server while in a call with Twilio number (agent)?
