Call hung up, cause:busy

I am trying to web call using asterisk, but outgoing call always hung up by saying it’s busy. In asterisk log, it gives the following errors. It happens after updating the SSL certificate, before that the call was working. What can be the possible cause? Please help me if anyone knows.

Your endpoint definition has an invalid transport configuration.

Thank you for your reply. If you don’t mind, can you please let me know, how can I change the transport configuration?

Configuration options for pjsip are in the wiki:

Okay. Thank you. I will try it.

Hello everyone,

I am sorry that I am asking this question again but now there is not any errors in asterisk but still the call isn’t working. Call always ended up saying busy. If anyone familiar with it, please let me know if you need any additional information, and what can be the reasons behind it?

provide us with more logs from your attempt as well as your pjsip configuration.

Thank you. I really appreciate your time.
I have attached the screenshot of asterisk log and pjsip configuration.

The configuration isn’t what I was expecting, what product are you using?

Asterisk does not have a GUI.

I apologize for that:
so my pjsip.conf is as below:
w3

pjsip.endpoint.conf
w4

and pjsip.transport.conf :w5
