I would tend to disagree that a policy of "Use UDP preferably
and switch to TCP if message is too big" is a good policy. Especially
considering that you'd have to keep the TCP connection alive anyways.
I believe that always using the TCP connection in this case would
make more sense.
But it's definitively legal.
I totally agree with this.
But from several years attending SIPit's I would highly recommend you to
NOT mix UDP and TCP. From time to time I had already interoperability
issues when my proxy did for example UDP to TCP conversion (and back).
If you are talking/thinking about an UA implementation which mixes UDP
and TCP on the first hop already I would anticipate lots of
interoperability issues down the road. You should at least attend a
SIPit to check how other proxy and UA implementations react on this. In
the end any benefits which you might get from this design decision might
be easily eaten up by the support efforts later.
