Hi Carsten, I did socat relay from TCP to SCTP and Diameter caps exchange seems to happen. But CDP module still refuses to use this connection/peer: AAASendMessage(): AAASendMessage(): Can't find a suitable connected peer in the routing table. 0(1) ERROR: cdp [routing.c:275]: get_routing_peer(): get_routing_peer(): No connected DefaultRoute peer found for app_id 16777216 and vendor id 10415. I suspect something wrong in the xml config for CDP I got: <DiameterPeer .... <Peer FQDN="10.47.10.153" Realm="ims.mncXX.mccYYY.3gppnetwork.org" port="7868"/> <DefaultRoute FQDN="10.47.10.153" metric="10"/> </DiameterPeer> And this is HSS's response: [image: Inline image 1] Thanks, Sergey. 2017-03-03 17:14 GMT+01:00 Carsten Bock &lt;carsten(a)ng-voice.com&gt;om>:

Hi Carsten, Does this look ok on i-cscf: kamcmd cdp.list_peers { Realm: ims.mnc06.mcc240.3gppnetwork.org Identity: icscf.mnc06.mcc240.3gppnetwork.org Accept unknown peers: 1 Connect timeout: 5 Transaction timeout: 5 Default auth session timeout: 3600 Queue length: 32 Workers: 16 Peer count: 1 Peers: { FQDN: 10.47.10.153 Details: { State: I_Open Disabled: False Last used: 0 Applications: { appid:vendorid: 16777216:10415 } } } } Thanks, Sergey.
