[SR-Users] CRLF Error with tcp_crlf_ping

[Daniel-Constantin Mierla]

Hello,

is kamailio sending crlf after the second crlf from the client?

There is no notion of a packet in a stream connection, even a sip packet 
can be send char by char and the server has to assemble it by keep 
reading in a local buffer until all is retrieved.

Cheers,
Daniel
