At the end of the output you sent me, there are the following lines :
  fragment error in outer IP header
  error while compressing with the profile, using uncompressed profile
  uncompressed profile not found, giving up

That means that your 1500-byte IP packet is an IP fragment. The ROHC
protocol and therefore the ROHC library do not support compression of IP
fragments with the IP-only, UDP or RTP profiles. Only the Uncompressed
profile supports IP fragments. The last line show that the Uncompressed
profile is disabled, so compression of your 1500-byte IP fragment is
impossible.

To fix the problem, enable the Uncompressed profile or do not compress
IP fragments.
