...---snip--- Patch SRTP for 32bit SRTP have a cryptographic hash to check the integrity of the encrypted packets. It support two hash size: ? 32bit ? 80bit In order to properly fine tune SRTP for mobile networks and to have compatibility with PrivateGSM Enterprise we must use SRTP with hash at 32bit (HMAC_SHA1_32). Asterisk 1.8 by default does not announce in SDP both 32bit and 80bit, but only the 80bit version even if both are supported. This very small 1 line patch make Asterisk by default work with SRTP hash at 32bit . Download the patch for HMAC_SHA1_32 RTP crypto offer 48. wget http://sourceforge.net/p...
