Alexander: I faced issues with stupid devices unable to handle fragmen-
ted UDP packets several times. TCP would help, however as Iñaki wrote it
also has some drawbacks. I tried to write down some suggestions on how
to solve this issue:

This is not what a proxy should usually do - but, honestly: who cares if
it helps? I'm doing so on my productional systems (OpenSIPS 1.6), and I
didn't meet any issues so far.

Iñaki, others: I'm pretty curious about your valued opinion on this - as
you definitively have deeper SIP knowledge than I do.

Cheers,
Thomas
