What Do I Do If a Page Embedded in the CEC Cannot Be Opened?
Symptom
After an inbound call screen pop-up is configured, the integrated enterprise page cannot be displayed in the CEC, and an error is displayed, indicating that the setting of X-Frame-Options is incorrect. Figure 1 shows a possible error.
Solution
This product uses iFrame to integrate enterprise pages. To integrate HTML pages, X-Frame-Options can be set only to a non-specific value or ALLOW-FROM URI, where URI indicates the URL of the CEC.
X-Frame-Options in the HTTP response header indicates whether a page can be displayed in <frame>, </iframe>, or <object>. This function allows a website to ensure that its content is not embedded in other websites, as shown in Figure 2.
Before integration, use the development tool to check the value of X-Frame-Options on the enterprise page to be embedded. The options are as follows:
- DENY: The page cannot be embedded in any page, including pages with the same domain name.
- SAMEORIGIN: The page can be embedded only in pages with the same domain name.
- ALLOW-FROM URI: The page can be embedded in the specified page.
- None: The page can be embedded in any page.
If the value of X-Frame-Options of the enterprise page is DENY or SAMEORIGIN, choose
, click Edit, and set Open Mode to Independently opened in the Modify Incoming Call Screen Pop-up dialog box.Feedback
