some calls that use rtpengine produce "SRT[C]P output wanted, but no crypto suite was negotiated" syslog messages. below is an example. the messages seem to appear after rtpengine has replied to offer request, but before it has got answer request that includes crypto suite negotiation in its sdp.
the calls work fine and i was wondering if these syslog message are really needed?
