If you outgoing calls are successful when made from CTI client, but not from the CRM entity, simply check the Internet Explorer Security Options. Please make sure that your CRM Server is included in the Trusted Sites Zone.
If it is correctly added, but it still does not seem to triggers any reaction, please activate debugging and erase all existing logs.
Then, try an outgoing call from within your CRM entity and send the log file to email@example.com.
That’s it! We appreciate your feedback! Please share your thoughts by sending an email to firstname.lastname@example.org.
