Twilio/ Salesforce Softphone not working

[subhodeepDey]

Hi,

I've installed Twilio in one of my client's Org. And followed all the steps of configuration(https://moometric.com/integrations/sf/salesforce-open-cti-lightning-with-twilio-tutorial/).

But facing the same issue mentioned in the above link,

Issue:

Uncaught Error: Unable to make a call. Contact your admin. throws at https://alu--tfsb2--c.cs85.visual.force.com/components/c/callInitiatedPanel.js:57:37

Please help me with fixing this issue.

I've one more requirement on same Twilio, If a number is dialed from the dialer or any outbound call is in progress with the Twilio and the receiver won't receive the call or call get disconnected then there should be a pop-up message with the reason on the dialer screen.

Thanks!
