[OpenSER-Users] T.38 and RTP Read too short

9 Jul 2008

Hey everybody,

I use OpenSER (openser 1.3.2-tls (x86_64/linux), svnrevision: 2:4420) 
and the RTPproxy (1.1) and everything works fine expect for one thing.

If I try to use T.38 with following scenario:

SIP-FAX1 (NAT) <-> RTPProxy+OpenSER <-> Asterisk <-> Carrier

the Asterisk always produce this kind of warning:
'WARNING[1493]: rtp.c:1145 ast_rtp_read: RTP Read too short'.

The SIP-signaling with the re-INVITE works fine. If I get an re-INVITE I 
call the force_rpt_proxy( 'l' ).

Has anybody an idea what I should change in the RTPproxy to get this 
scenario working?

Thanks for your help,

     Jens
