Hello Henning Westerholt,
First of all thanks for your fast answer, as you mentioned I had not
defined that xml file but I have defined three xml for each node (that
are referenced in kamailio.cfg also one per node) that contains the
DiameterPeer information and for the icscf.xml this is the parameters:
<?xml version="1.0" encoding="UTF-8"?>
<DiameterPeer
FQDN="icscf.net1.test"
Realm="net1.test"
Vendor_Id="10415"

<Acceptor port="3868" bind="127.0.0.20"/>
<Auth id="16777216" vendor="10415"/>
<SupportedVendor vendor="10415" />

<!--DefaultRoute is needed for vendor=0 -->
</DiameterPeer>
For the node P-CSCF this is the XML file:
<?xml version="1.0" encoding="UTF-8"?>
<DiameterPeer

<!--DefaultRoute is needed for vendor=0 -->
</DiameterPeer>
And for the S-CSCF:
<?xml version="1.0" encoding="UTF-8"?>
<DiameterPeer

<Acceptor port="3868" bind="127.0.0.22"/>
<Auth id="16777216" vendor="10415"/>

<!--DefaultRoute is needed for vendor=0 -->
</DiameterPeer>
Maybe this could help to find the answer to my problem. Thank you a lot.
Kind regards,
