[Srtp-users] Failed Authentication on ~10-40% of calls on certain phones

[Burton S. <bsamograd@Interalia.com>]

Hello,

 

I have integrated libsrtp into our SIP product and it works relatively
well.  I am having a 

problem where, on 2 out of 3 phones I have tested with,  authentication
is failing on the 

SRTP packets, on one phone about 10% of the time and on the other phone
upto 40%.

I have enabled debug printing and other than the packed and computed
authentication 

tags being different I cannot see any other errors.

 

Could this be due to SSRC values that are not in an appropriate range?
Could there be 

anything else that is affecting these 2 phones and not the other?  Any
ideas on why the 

authentication fails on only a certain percentage of the calls?
