Hi everyone
I have a small question:
i want to set up a basic SIP Redirect Server
so I install Kamailio v5.3
and comment default request route and set simple
request_route {
rewritehostport("1.2.3.4");
sl_send_reply("302", "Moved Temporarily");
}
but for some reason, Kamailio does not care about the port and sends a
reply to 5060
[image: image.png]
i also tried to delete rewritehostport
but it only deletes Contact: from the reply
but reply itself is still sent to 5060 port

Please close request as I found out that this is required behaviour
according to RFC

Kind of depends on which RFC you’re talking about.
As Fred asked – do you have `force_rport` set? This is defined in
RFC3581<https://www.ietf.org/rfc/rfc3581.txt>xt>. In an *ideal* world, your UAC would
put the `rport` parameter (without value) in it’s Via header. Kamailio can be told to
“consider this request like there’s an `rport` in the top most via header” by setting
`force_rport`. This is what you want based on your description below.

Kaufman

As I was involed in this conversation via other channel, some comments on
this to the community.
1. Kamailio is acting according to these parts of 3261 -
https://www.rfc-editor.org/rfc/rfc3261.html#section-18.2.1
If the host portion of the "sent-by" parameter
contains a domain name, or if it contains an IP address that differs
from the packet source address, the server MUST add a "received"
parameter to that Via header field value. This parameter MUST
contain the source address from which the packet was received. This
is to assist the server transport layer in sending the response,
since it must be sent to the source IP address from which the request
came.
Consider a request received by the server transport which looks like,
in part:
INVITE sip:bob@Biloxi.com SIP/2.0
Via: SIP/2.0/UDP bobspc.biloxi.com:5060
The request is received with a source IP address of 192.0.2.4.
Before passing the request up, the transport adds a "received"
parameter, so that the request would look like, in part:
INVITE sip:bob@Biloxi.com SIP/2.0
Via: SIP/2.0/UDP bobspc.biloxi.com:5060;received=192.0.2.4
2. And forming a responce without force_rport() according to this
https://www.rfc-editor.org/rfc/rfc3261.html#section-18.2.2
Otherwise (for unreliable unicast transports), if the top Via
has a "received" parameter, the response MUST be sent to the
address in the "received" parameter, using the port indicated
in the "sent-by" value, or using port 5060 if none is specified
explicitly.
So, the question was mainly why responce is sent back to the source
address, but to a different ("default") port.
Consider this as a reading RFC 3261 outloud once again )
