Re: [Sip] I-D on handling large UDP responses

We might be able to reduce the number of 140's by having the proxy in

indicating "140 already sent for this request". Then a proxy would
not generate a 140 for a request that had this flag on a Via.
This is interesting -- but if a proxy, P1, switches to TCP from UDP,
and sends a 140, then chances are that all proxies downstream from
P1 will use TCP as well (for the same reason that P1 did -- the
request was over 1500 bytes).
So, a 140 should happen only once, and not at every hop.
