ASA Phone proxy

leslie-meade — Mon, 11 Mar 2019 22:14:06 GMT

I seam to have two issues here and would like to get some thoughts on it

1st I am getting this error, but it is defined in the phone proxy.

SNP_SRTP::Error:media_session not found!!

2nd i am getting this error when the phones connect.. but it seams not to have issues with the phone working, as i see the debugs say ssl handshake succesful...

%ASA-7-725014: SSL lib error. Function: SSL3_READ_BYTES Reason: ssl handshake failure

any ideas ?

Hi Leslie,

If you see the SSL handshake failure but the phones are still able to register, they are probably registering unsecurely (i.e. not though phone proxy).

You'll need to resolve the secure registration/SSL issue before taking care of the media issue. Do your phones have a MIC or LSC installed? Also make sure that you have the appropriate trustpoints setup on the ASA.
