When I made the blank settings of value, type of
<param name="tls-verify-in-subjects" value=""/>
the check of peer name in the manner
<param name="tls-verify-policy" value="subjects_all"/>
works good.

The same favorable outcome I can observe if value settins are of kind
<param name="tls-verify-in-subjects" value="sip.obolenskaya.su"/>

that is to say pattern-matching filtering.

Now Peer Subject in incoming connection matches!

But I nowhere could find the similar clarifications.

Thank All!
