How to enable SRTP for SIP Trunk and SIP Phones?

[zyrk]

Hi Guys,

I see a "SRTP" option for the SIP Trunk but is it something as simple as enabling that? How can I enable SRTP for the SIP Phones? We are using Telnyx as our SIP Trunk provider and Yealink phones provisioned remotely with STUN.

Thank you!

So yes if you want to enable SRTP for the SIP trunk and IP phones then you check the SRTP boxes.
