Also, SNOM phones are systematically using port 2048 as source port of the

What do you mean? The initiator is free to pick whatever source port they like.
Well, how he will know that the port is free ?
bind() fails for listener socket, connect() fails for outgoing (if
everything is full).
On conntrack machine, connection tracking table gets queried after SNAT
to see if the new tuple is still unique.
Thanks to all for the explanation.
