It works pretty good.
But when I was testing such an implementation with imitation of high
latency (200ms) and packet loss(about 15%) voice over UDP worked much
better since TCP was trying to retransmit lost segments.
I think TCP_NODELAY must be always enabled to avoid packets
concatenation at sender's outgoing buffer to reduce latency.
Hello,
This was a concept raised in my mind and was looking for a lead or
hint to get started to work on routing rtp via tcp. ( On SIP phone as
well as Kamailio ). I knew through googling there has been such
implementation and thus to make sure it is an absolute possibility. So
here, I am just trying my luck to interact with developers who has
worked on such project, if any.
Warm Regards

Hi Daniel,
Its more of a customized encryption technique I am looking for.
that is a bit vague, maybe you can give some examples.
Nobody here did an invention on encryption techniques, if that is the
question. Otherwise, if you look for particular mechanism, even not
implemented, we can say if it can be done or not.
Encryption of SIP and RTP is already addressed as I can see from many
threads, but important part is whether is there any possibility of
routing rtp over tcp. Is it a possible concept or impossible task to
implement it on kamailio. I just want a lead about this concept.
Routing rtp via tcp is possible as technology, being pretty much what
happens with some VPN systems. But it is not only a matter of kamailio,
but also of SIP phone.
Cheers,
Daniel

Hello,
Any successful implementation of adding some customized security
(encryption) over sip and rtp in kamailio? (non TLS) Also looking for
assistance on the concept of rtp over tcp using kamailio and rtpproxy.
using VPN/ipsec tunnel is a way to get both sip and rtp encrypted
between two SIP nodes.
Other than TLS, Kamailio does not do any encryption for SIP. What
alternatives you would look for?
Cheers,
Daniel
