Unable to get login screen from Telephony toolbar



User has recently upgraded to PegaCALL on CPM 7.13 using Pega7.1.8 version.

On click on "Phone" option from the operator navigation menu on the interaction portal displays a telephony toolbar. On click on telephone icon user is getting nullPointerException on screen instead of a modal dialog with agent login screen.

Steps to Reproduce

  1. Launch the Telephony toolbar.
  2. Click on call icon of telephone bar.

Root Cause

The NullPointerException was due to the missing page or context as the user was launching the toolbar on the CPM portal using a callEventHandler JS, which is deprecated on PegaCALL versions.


Perform the following local-change: 
  1. Use OOTB approach to launch the telephony toolbar from the preferences menu. 
  2. Click on Operator Name > Preferences > Channels (Phone) > Enable phone tools upon login.
  3. Select the checkbox and save preferences to launch telephony toolbar which works fine.
