Extension not register with tls and srtp

[mohitbabu]

I have asterisk 18.20 on ubuntu

Have generated the certificates as mentioned in https://wiki.asterisk.org/wiki/display/AST/Secure+Calling+Tutorial . Also configured sip.conf accordingly, added the ca.crt and malcolm.pem in softphone but it is not registering. I guess its not authenticating.

Not sure if I’m missing something.

Please Guide me

You need to be more specific. Is it not able to connect? Is anything shown on Asterisk? What does the endpoint say? Does it connect but the REGISTER fails?

That log is clearly incomplete. Most REGISTER requests will receive a 401. The registrant will then resend with authentication information. However, 401 cannot be sent unless the REGISTER was received.
