TVOCancelledCallInvite Class Reference

Inherits from NSObject
Declared in TVOCancelledCallInvite.h

Overview

The TVOCancelledCallInvite object represents a cancelled incoming Call Invite. TVOCancelledCallInvites are not created directly; they are returned by the [TVONotificationDelegate cancelledCallInviteReceived:error:] delegate method.

Properties

  from

From value of the Call Invite.

@property (nonatomic, copy, readonly, nullable) NSString *from

Discussion

This may be nil if the notification passed in [TwilioVoiceSDK handleNotification:delegate:delegateQueue:callMessageDelegate:] method does not have valid information in it.

  to

@property (nonatomic, copy, readonly, nonnull) NSString *to

Declared In

  callSid

A server assigned identifier (SID) for the incoming Call.

@property (nonatomic, copy, readonly, nonnull) NSString *callSid

  customParameters

Custom parameters embedded in the VoIP notification payload.

@property (nonatomic, strong, readonly, nullable) NSDictionary<NSString*NSString*> *customParameters

Discussion

The custom parameters will be received in the notification payload with the twi_params key and in query-string format, e.g. key1=value1&key2=value2. To receive custom parameters on the mobile client, add <Parameter> tags into the <Client> tag in the TwiML response.

<?xml version="1.0" encoding="UTF-8"?>
<Response>
  <Dial callerId="client:alice">
    <Client>
      <Identity>bob</Identity>
      <Parameter name="caller_first_name" value="alice" />
      <Parameter name="caller_last_name" value="smith" />
    </Client>
  </Dial>
</Response>

The customParameters value would be:

{
    "caller_first_name" = "alice";
    "caller_last_name" = "smith";
}

Note: While the value field passed into <Parameter> gets URI encoded by the Twilio infrastructure and URI decoded when parsed during the creation of a TVOCancelledCallInvite, the name does not get URI encoded or decoded. As a result, it is recommended that the name field only use ASCII characters.
