[Serusers] why isn't xlog logging?

I must be doing something really dumb: if (uri==myself) { # allow *all* my aliases to match if (method=="REGISTER") { xlog("L_INFO", "REGISTER %is: %tu\n"); if (!www_authorize("columbia.edu", "subscriber")) { www_challenge("columbia.edu", "0"); break; }; save("location"); # save in usrloc break; }; Nothing shows up in syslog for the xlogs but other syslogging works: Jan 21 14:23:51 ren ser: Aliases: ren.cc.columbia.edu:5060 localhost:5060 localh ost.localdomain:5060 columbia.edu:* Jan 21 14:23:51 ren ser: Listening on Jan 21 14:23:51 ren ser: 127.0.0.1 [127.0.0.1]:5060 Jan 21 14:23:51 ren ser: 128.59.39.127 [128.59.39.127]:5060 Jan 21 14:23:51 ren ser: Aliases: ren.cc.columbia.edu:5060 localhost:5060 localh ost.localdomain:5060 columbia.edu:* Jan 21 14:23:51 ren ser: ser startup succeeded Jan 21 14:24:09 ren /usr/sbin/ser[23883]: ACC: call missed: method=INVITE, i-uri =sip:43754@columbia.edu;user=phone, o-uri=sip:43754@128.59.59.242:5060;user=phon e, call_id=00036baa-c49ce019-38332009-0bf6c446(a)128.59.31.170, from="alan" <sip:a lan(a)columbia.edu&gt;;tag=00036baac49c014725d2d806-0cc644f04f0, code=487 Request Termin ated version is ser-0.8.12 /a
