Thanks Gonzalo,

That setup on the FS side refers to TLS and as I said TLS is working for me, I have it set up.  

SRTP should work out of the box AFAIK.  I suspect there is something in the SDP I posted that FS considers to be non-compliant with the specs.  Not sure what though and whether it's a bug in FS or in the client SDK I am using.

Did you enable/configure SRTP? This is a sample guide I use for Twilio TLS/SRTP which can help

Can you post all logs?

Hi guys,

I am trying to connect to FS using the CounterPath SDK for Android.  I use TLS for signalling.  All works well until I try to enable SRTP.  Then FS rejects the call the INCOMPATIBLE_DESTINATION message.  Is there something wrong with the SDP?  Here are the relevant SDPs from the INVITES.
