I've been recently playing, with success, with kamailio IMS modules and the examples *cscsf configuration files. Now I'm trying to implement qos but I am stuck with diameter routing. Basically I can route Rx requests only if I use "rx_forced_peer". In the other cases (Realm routing or default routing if I have no realm-specific configuration) cdp module seems not to be able to find a route. 

What I have in the logs is

"Checking if peer XXX handles application 16777236 for vendord 0" (realm routing)

or

"get_routing_peer(): No connected DefaultRoute peer found for app_id 16777236 and vendor id 0." (for the default route).

Looking at get_routing_peer function (cdp module) it seems that the function extracts the vendor_id either from grouped Vendor-Specific-Application-Id AVP or from Vendor-Id AVP if in the request the Auth-Application-Id AVP is present. In this case, even if Vendor-Specif-Application-Id is present, it's not taken in count by the routing logic. In the AAR generated by ims_qos there is the Auth-Application-Id AVP but not the Vendor-Id, so the vendor_id for which cdp module looks for is "0" which is not found in any of the connected peer.

Am I missing something (probably)?

Thank you and have a nice weekend.
