Hi, I have setup kamailio with the dispatcher module and have a problem
with the ACK in response to 200OK not being forwarded by kamailio:
Scenario is very simple:
sipp(.219) --> kamailio (.220) --> sipp(.239)
SIP trace:
root@DNS-enum-8Gb-3:/var/log# ngrep -W byline -d eth0 port 5060
interface: eth0 (10.57.26.0/255.255.255.0)
filter: (ip or ip6) and ( port 5060 )

Hi, I have setup kamailio with the dispatcher module
and have a problem
with the ACK in response to 200OK not being forwarded by kamailio:
Scenario is very simple:
sipp(.219) --> kamailio (.220) --> sipp(.239)
SIP trace:

Wim,
Looks like your ACK is missing the Route header, since ACK is a new
transaction kamailio needs to route it based on a preloaded route. When
you receive the 200OK in sipp you should save the record route set and
use it in the ACK with the "[routes]" statement.
Take a look at the SIPP docs and search for rrs="true". If you take a
packet capture on the loopback interface of the kamailio server you will
probably see that kamailio keeps looping the ACK until the Max-Forwards
is exhausted.
Example:
<recv response="200" rtd="true" rrs="true">
</recv>
<send>

Hi, I have setup kamailio with the dispatcher module
and have a problem with the ACK in response to 200OK not being forwarded by kamailio:
Scenario is very simple:
sipp(.219) --> kamailio (.220) --> sipp(.239)
SIP trace:

Wim,
Looks like your ACK is missing the Route header, since ACK is a new
transaction kamailio needs to route it based on a preloaded route. When you
receive the 200OK in sipp you should save the record route set and use it
in the ACK with the "[routes]" statement.
Take a look at the SIPP docs and search for rrs="true". If you take a
packet capture on the loopback interface of the kamailio server you will
probably see that kamailio keeps looping the ACK until the Max-Forwards is
exhausted.
Example:
<recv response="200" rtd="true" rrs="true">
</recv>

Hi, I have setup kamailio with the dispatcher module and have a problem

Scenario is very simple:
