Hi, in URI as "ping(a)domain.org" I need to change URI to just "domain.org" (without the username@). But I have multidomain so can't rewrite uri directly and must use the requested URI domain ($rd). So I try: if (uri=~"sip:ping[@]+.*") { rewriteuri("sip:$rd"); xlog("L_INFO", "-- New URI = $ru\r\n"); ... but I get: -- New URI = sip:$rd so it seems that I cannot use variables for making function parameters, is it true? so then, how should I do it? maybe I need using AVP's for that? Thanks for all. -- Iñaki Baz Castillo ibc(a)in.ilimit.es
