Open up vars.xml in 1.6.18 or master repo, and read the outlined SRTP documentation.

Hello All,

I had the following issue:

issue is here :[WARNING] switch_core_media.c:4451 Crypto not negotiated but required.
This is the log for my issue. The external forwarding does not work when I use rtp_secure_media=true. Everything else works. The only workaround is to put rtp_secure_media=false in the outbound dialplan and make the bridge=loopback instead of outbound. I don't like this workaround. Is there a more elegant solution?
I want the bridge=outbound and not loopback

Then I was told that I can use rtp_secure_media=optional

It made me happy as I thought the problem is solved.


But now the problem is rtp_secure_media=optional does not work when the devices only have SRTP_Encryption =ALWAYS or NEVER where the "Optional" is not an option and they cannot receive calls. I know that we can separate inbound and outbound. However, forwarding is both inbound and outbound.

John,

what exactly is your problem?

What is that you want to achieve?

What dialplan, what endpoints?

What you exactly do, how we can reproduce the problem?

Please state all the step we need to replicate your problem.

Do you have a solution for me?


With my thanks,

John McPherson
