Hello everbody, I loaded module "uri" and my ser.cfg is as below: ..... loadmodule "/usr/local/lib/ser/modules/uri.so" ..... if (method=="INVITE") { if (!radius_proxy_authorize("iptel.org")) { proxy_challenge("iptel.org", "1"); break; } if (!check_from()) { sl_send_reply("403", "Forbidden"); break; } } ........ When I run ser, it says: 0(10457) find_export: <check_from> not found 0(10457) find_export: <check_from> not found 0(10457) parse error (183,35-36): unknown command, missing loadmodule? Can you see what am I doing wrong ?? Thanks in advance Regards Tulay ______________________________________________________ Yahoo! for Good Watch the Hurricane Katrina Shelter From The Storm concert http://advision.webevents.yahoo.com/shelter
