Thanks Jan, I traced where the problem was, with regards to the ser.cfg ser restarts fine thanks. I am now trying to work on the zone file, quick question; would I be editing, the localhost.zone file in /var/named using vi or is there an easy way of doing it, how would I set this, any ideas. I am looking for this info. _sip._udp SRV 0 0 5060 gateway.mydomain.com

Another thing I tried logging in using WM 4.7, does not recognise my server (sipserver.ipaxiom.com), hence entered the IP and it found the server, however when enter the user details I get is signing in session for a while which then times out. Is what I should be expecting?? Any ideas.
