Anyone familiar with:

ims_diameter_server

cdp

cdp_avp


I have set Kamailio up to connect with SMSC using Diameter.

Initially just want to capture requests in JSON and examine. My trace 
tells me that I am sending a good message for DIRECT_DEBITING (436).

I know the ocs module does not support this - only trying to "take 
apart" the message. When I get the message, I experience the following:

FebĀ  7 13:07:58 ip-172-31-45-179 /sbin/kamailio[18048]: ERROR: cdp 
[diameter_avp.c:645]: AAAUngroupAVPS(): hss3g_ungroup_avps: source 
buffer to short!! Cannot read the whole AVP header!
FebĀ  7 13:07:58 ip-172-31-45-179 /sbin/kamailio[18048]: CRITICAL: cdp 
[diameter_avp.c:702]: AAAUngroupAVPS(): AVP:<>

I suspect this is due to vendor, but not experienced here. The docs seem 
to suggest the 3gpp is supported, and the diameter xml is set for 0 & 10415?
