TLS SIP Trunk (2Talk)

Hi,
I'm running Hosted FreePBX 13 and trying to configure a TLS SIP Trunk so that the communications is encrypted all the way from my endpoints to my service provider. I am currently using 2Talk as my service provider. I have been in contact with 2Talk and they say they support connections over 5060 and 5061 (TLS). The problem is that I do not know how to configure FreePBX to connect using port 5061 for the trunk. (I have successful TLS connections to Sangoma phones.)

Also, I do have a successful connection over 5060 to 2Talk using these guidelines: https://www.2talk.com/siptrunking.html
But no example from them using TLS. (They just told me I could try tls.2talk.com but still isn't working for me.)

The error I get in the logs when I attempt a call on the trunk over port 5061 is:
[2017-09-28 16:15:22] VERBOSE[2496] tcptls.c: SSL certificate ok
[2017-09-28 16:15:22] ERROR[2496] tcptls.c: Certificate did not verify: unable to get local issuer certificate

While happening to get the exact settings I would need for 2Talk service would be ideal, recommendations from others who have accomplishment a TLS connection with their service provider may help shine some light on what needs to be done.

Thanks in advance for the help!
