David Bernard Posted January 27, 2009 Report Share Posted January 27, 2009 Hello, I have a question regarding SRTP/SDES. Is it possible to configure pbxnsip to use SDES with a SRTP authentication tag length of 80 bits (AES_CM_128_HMAC_SHA1_80) by default? Because of what I see, it uses a tag length of 32 bits (AES_CM_128_HMAC_SHA1_32), even if 80 bits is supported for incoming calls. For information, I am testing pbxnsip version 3.1.2.3120 (Win32).

IMHO the 80 bits are just overkill, why would you need it? Quote Link to comment Share on other sites More sharing options...
