-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm running Asterisk 11.3.0 on wheezy. I'm trying to do TLS +SRTP with blink SIP clients as shown here https://wiki.asterisk.org/wiki/display/AST/Secure+Calling+Tutorial. TLS is fine and I can call between clients. SRTP is a different matter, my SIP clients return: SIP 488 "Not acceptable Here" I'm really stumped on this one, any ideas? srtp module is loaded: *CLI> module show like res_srtp.so Module Description Use Count res_srtp.so Secure RTP (SRTP) 0 1 modules loaded extensions.conf extract exten => 1002,1,Set(_SIPSRTP=${SIPPEER(1002,srtpcapable)}) exten => 1002,n,Set(CHANNEL(secure_bridge_signaling)=1) exten => 1002,n,Dial(SIP/exten1002,20) exten => 1002,n,Hangup() sip.conf extract: [exten1002] type=friend host=dynamic secret=averygoodone context=users nat=force_rport,comedia encryption=yes transport=tls Thanks, Regards, John -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJRWHYgAAoJEJDWDcq/312/p5UQALIwM8RfmUyEI4TRcvNOOvkQ ckUeIz5wUGO3/wNAJBUgNwAypho7kGcahzthdmFWxwk1jUuGiHLbvZQ0Z44oyKpp h0pfBeg78Zay1ZRRgrsdF91/Rcw7yJarQsftJCkDwKM+aw2MezaiHjE5YLj2/aMC z+2FWI44XEGL0CGeUPoeTQWwDOd1gHIk1CNqEeQD28E3n7EBCyYU/34+cFdWHm2A yVAAFELDXWKsnklDtw6wNQtJLVsTsGlmDXv7FsQjyBt6dcL+NZMFCqc4/UdAxTxS n2hrFgP1YVzDeVPpSxgEdY0LMQC0vQ12jb9DjzsJ6wAnZicBwmdVpst+043mQNU6 YhMTAGki7QpsLzsmZXDMXUOzzWoGNw2ePYt+gw7VoQfUI0KXc5PwbA2mfJnrM9Fs QbvNYUHyjENKsE+7890J7/v+4/Bi5bm8Nyt7SZFZK98TI+x71I2P7Bqbe5yGmWd7 C5qYbDvp+3j+9tM7K5v84VRKSOTz5/9XfF67CXof35staPdpQAGO9L8o/OrCHwrW +M7sjTYBVXOLFbTty/tnFMzQjwEW/SRMdM4SaW1NVf8WJKAR7T5Kw+pv1ggv8GpA fyZRfp9UHZIrRAUoCiSPjyTDm4P/HvJfioDa6hTcwVTgStz5fFxXUXjWdBUNpzP0 fyxVa7F045BBD6SlpsS0 =Grot -----END PGP SIGNATURE-----
