I have defined three asterisk sip extensions, all in the "default" context. I have two of them assigned to support reps (one is administrator, another one a support rep created by me). All three extensions are registered in asterisk and dialing from any of them to any other works perfect. Click-to-dial works on both extensions assigned to support reps (and I get the on-screen pop for the outgoing call).

The problem is now when I log with a support rep and call the extension assigned to it. Call is fine but I get no pop-up.

I have monitoring server-wide enabled and I have the pop enabled for the support reps. Using ManageEngine SupportCenter Plus 7.6.0 on a Trial License.
