Yes. But the DNS expire time is 5 minutes so I
would go by the higher
number.
this?
We only support 3 UACs on our network. ATA, BT, SPA and it works on all 3.

One issue here could be
We use DNS updates.
So, whats the expire setting in your zonefile? that some large ISPs doesnt honor small expire
settings in zone-files
and clients using such a dns resolver _wont_ get an updated ip-address
but get hung on the old one.
That is a possibility, But so far we have not encountered it and we have
clients in 10 countries. In any case if it works for only 95% of customers
then we will be quite happy. So far it has worked for 100% of our
customers.
We have
special scripts based on sipsak (Thanks Nils!),
that check all SIP servers every minute.
So failover time is one minute?!

Youre _sure_ that every UAC will do this? With wich UACs did you test
