Hello, I have a small configuration file containing just the following lines in the route block: $var(domain1)="sip:+491@example.com"; $var(domain2)="sip:491@example.com"; if( $(var(domain1){uri.user}{re.subst,/^\+//}) == $(var(domain2){uri.user}) ) { if ($(var(domain1){uri.domain}) == $(var(domain2){uri.domain})) { xlog("L_ERR", "TEST OK"); }else { xlog("L_ERR", "TEST FAILED"); } } The user check is ok, but somehow in 1.5 the domain check fails. I have dug a little deeper and it seems that when comparing the uri.domain str's they are wrong(it compares xample.com to example.com, but the length of the str is still 11). The only way I could replicate this was with the use of a re.subst expression. I guess this is the culprit, as removing it fixed the problem. Any ideas on why this happens? I didn't manage to replicate in ser, will try in kamailio 3.0. Marius
