hey,
I don't know anything specific to this case, but you'd serve your best interest to send small enough packets that do not need fragmentation, particularly in the backbone.
In this case the SIP invite is already sent fragmented from the source and no fragmentation is required in transit. Someone probably thought "we see a lot of DDOSes with UDP fragments, better drop them altogether". -- tarko
