Hello All, *I had the following issue:* https://pastebin.freeswitch.org/view/8722d895#L30 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.* Do you have a solution for me? With my thanks, John McPherson
