<p class="MsoNormal">First off, I'm wondering why it says "no ipv4" in front of your two addresses. That might be your problem right there.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>

<p class="MsoNormal">Secondly, I'd recommend putting an explicit preference on your entries, it's just better for everyone, and you don't get a credit back from Cisco for saving on a few ascii characters by implicitly using the default. Plus, if the default
is 0, which it is, then your next preference should be technically 1. But then having nothing and 1 seems silly, because if pref 1 is actually pref 2, then well, might as well call them pref nothing and pref 8. I digress.<o:p></o:p></p>

<p class="MsoNormal">You might not have failed over, because you might not have provided the system with the correction conditions to failover...E.g., you didn't wait long enough.<o:p></o:p></p>

<p class="MsoNormal">No seriously, by default SIP failover occurs after 30 seconds. Unless, did you lower the retry count under sip-ua? Or did you enable SIP options? If you enabled SIP options, have your confirmed that it's turned on correctly?<o:p></o:p></p>
