I'm reporting back to user's list as that would be the best place for this question. This looks like the registration servers are replicating properly. DNS is probably the issue but i don't think you need upstream DNS configured. Often each server has a local caching DNS server that is screwing things up. Try these commands *from each and every server* to make sure each server get the appropriate values dig -t SRV _sip._tcp.your-domain-here See http://wiki.sipfoundry.org/display/sipXecs/DNS+Verification Ultimately supervisor or registrar logs will have the errors, but sometimes they can be vague or cryptic, but post them back and i know how to translate a few of them by now. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
