With rtcachefriends turned on, the realtime peer is cached in memory.  Therefore, in order to clear the cache for that peer, you should check into issuing the command "sip prune realtime peer <peername>" if you want to clear out only the one peer.  If you want to reload the peer back in memory after clearing it out, you can issue "sip show peer <peername> load" to load it back from the db.
