I m using cent-os 6.2, kamailio-5.1.2 and openims-hss.

I am using rtpengine to relay voice, but I  am unable to send files or chat messages using it.

I looked at rtpengine logs, it was saying unknown codec for chat and file-transfer requests. Then,  I thought of using Kamailio msrp , tried but no success.  Does current Kamailio IMS support file transfer? If so, please give me suggestions on doing it.
