I have enabled properly SRTP and tls on the phone snom 715 on my PBX 3CX. I'd analyzed the traffic and the connection is in TLS. On the phone i see the padlock that indicates the safety is active, but when i try to make a call between two snom in SRTP mode, the caller don't fell anything.
Please help me
I converted your request to a support ticket and merged it with existing one.
We will pursue the issue further there.
