Issue connecting to FS with SRTP
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.

Did you enable/configure SRTP? This <http://twilio-marketing-prod.elasticbeanstalk.com/resources/images/docs/TwilioSecure-Freeswitch.pdf> is a sample guide I use for Twilio TLS/SRTP which can help Can you post all logs? On Tue, Aug 16, 2016 at 6:10 PM, Oleg Stolyar <olegstolyar@gmail.com> wrote:

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.
