[asterisk-users] repeating TLS error in log file

[Kevin Long]

Greetings,


I use TLS and SRTP on all my extensions.  I use openssl and distribute my root certificate to my endpoints.   Most of the time my calls work just fine.  

Sometimes I receive a repeating error in my log files however, and I don’t know why this is happening. I’m wondering if this is really from the TLS connection for SIP, or an underlying error with SRTP decoding..   I sometimes get this message in the log when things seems to be working fine.  Is there a better way to debug exactly why I’m getting this error? Sometimes I have dozens of these errors in a row.

My openssl certificate chain checks out fine  with openssl verify command ..
