Outbound calls via TLS not working

[Catharsis68]

Issue: Outbound calls over TLS/SRTP are not working anymore

First time we faced the issue: 0.8.25 Latest image I have tested: 0.9.0

Carrier setup:

• Twilio
• TLS enabled
• Port 5061
• TLS/SRTP

Sample Gateway in the screenshot

In sbc-outbound we see this error when creating a call via API:

{"level":30, "u":"sip:[email protected]:5061;transport=tls","msg":"using SRTP for outbound call, pad crypto: no"}

log from drachtio server would be needed

[davehorton]

is there a reason you are using sip rather than sips as the scheme?

I believe this has been resolved.
