[Linphone-developers] Re: Error Msg about rtp_session_send_with_ts

[Simon Morlat]

Hi,

The ethernet maximum tranmission unit is often below 1500 bytes, so 40k is 
definetely too much. IP/UDP can sometimes make automatic fragmentation of long 
messages, but in your case seems like the kernel decided that 40k was defintely 
too long.
You should fragment your data to be carried over multiple RTP packet, that's 
how we do for video transmission for example.
