[Serusers] xmlrpc calls

I am currently trying to do an xml-rpc call to usrloc.show_contacts. The xml packet I am sending is the following POST /RPC2 HTTP/1.0 User-Agent: Radio UserLand/7.1b7 (WinNT) Host: localhost:5060 Content-Type: text/xml Content-length: 131 <?xml version=\"1.0\"?> <methodCall> <methodName>usrloc.show_contacts</methodName> <params> </params> </methodCall> As a return packet I am getting HTTP/1.0 200 OK Via: SIP/2.0/UDP 127.0.0.1:32769 Server: Sip EXpress router (0.10.99-janakj_experimental (i386/linux)) Content-Length: 303 Warning: 392 127.0.0.1:5060 "Noisy feedback tells: pid=5820 req_src_ip=127.0.0.1 req_src_port=32769 in_uri=/RPC2 out_uri=/RPC2 via_cnt==1" <?xml version="1.0" encoding="UTF-8"?> <methodResponse> <fault> <value><struct> <member><name>faultCode</name> <value><i4>400</i4></value></member> <member><name>faultString</name> <value><string>More Parameters Expected</string></value></member> </struct></value> </fault> </methodResponse> This tells me that I am not entering the correct information, but I am at a loss to exactly what else I should be inserting. I did a search for rpc_show_contacts and found in ./sip_router/modules/usrloc/ul_rpc.c static void rpc_show_contacts(rpc_t* rpc) After searching some more I could not find the rpc_t structure. Does anyone know what values I should be passing via XML? Thanks, Zach Keatts Software Engineer Nuvio.com
