Hi Juha,

The NOTICE message indicates that there is no entry in the hastable for 
the *(callid, viabranch)* pair, and the node selection algorithm will 
start running (select_rtpp_node_new()). This means that a new entry will 
be added in the hastable, containing the selected node for the pair.

The above is applicable for the delete() also, meaning that maybe other 
node could be selected than the one for the offer() and the call not 
being deleted properly from the original, offer() node.

IMO, the logs can go LM_DBG, because the info is useful when trying to 
debug a rtpengine call.

Regards,
Stefan
