                    What would you suggest? we are ISP, subnet migration

                    not be a problem but this will resolve down time as

                    <br>
                    What about DNS srv. This would not be a problem with
                    zones<br>
                    as need time to refresh (i just did I quick look to

                        &gt; Hi Miha,<br>
                        &gt;<br>
                        &gt; I would suggest two ways. The first is to
                        use the RFC3263<br>
                        &gt; and implement DNS<br>
                        &gt; redundancy using DNS SRV and NAPTR. The
                        only other way<br>
                        &gt; that I know is using<br>
                        &gt; BGP and migrating the IP address to another
                        server. You<br>
                        &gt; will need to have<br>
                        &gt; an AS to do this. It can be implemented by
                        a good (if he<br>
                        &gt; is willing to do<br>
                        &gt; that) Internet Provider.<br>

                        &gt; &gt; Hi,<br>
                        &gt; &gt;<br>
                        &gt; &gt; i need a little help or information
                        about geographic<br>
                        &gt; redundancy.<br>
                        &gt; &gt;<br>
                        &gt; &gt; What would be the best way to achive
                        that? If use<br>
                        &gt; opensips for<br>
                        &gt; &gt; registration and all users are
                        registered with domain I<br>
                        &gt; can change record<br>
                        &gt; &gt; in DNS server but this will need time.<br>
                        &gt; &gt;<br>
                        &gt; &gt; What would be the best way to achive
                        this with minimun<br>
