Hello, Only ROHC packets are allowed to transit between the he ROHC compressor and the ROHC decompressor. The ROHC decompressor assumes all incoming packets are ROHC packets therefore you can't give to it a IP packet. Maybe the uncompressed profile is a little confused. When the ROHC compressor is using the uncompressed profile, the IP packets are transformed as ROHC packets (a header is added - RFC3095 - Page 126).
