[SR-Users] rtpengine "SRT[C]P output wanted, but no crypto suite" messages

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?
