Thanks to everyone that replied. Here's some answers to the questions
asked;
Phone useage; We run an analog phone switch with five lines in a rolling
group plus a fax/dsl circuit. Stats from switch show we haven't used more
than three lines concurrently for the last year. Most usage is in local
extended calling areas with 30% being long distance out of state/country.
It doesn't appear that voip can work as a rolling group and no statements
as to whether the lines will work with an analog switch.
Our existing dsl service is 3mbps/768kbps. The same service with static
ip in a residential charge is $179 a month cheaper. We can get extra 5
ip's for $20 per month. We cannot have mail (mx) pointed to our static
since that needs an A record also, and apparently port 25 is blocked on
residential services. loking at Dynamic dns services but the charges
would reduce the cost savings.
I'm testing the MS POP3 connector for exchange 2000 with an isp based
account held wth our web hosting and it seems to work ok, and no change
in our exchange/outlook apps or real world changes in delivery times.
Since the majority of our business is transacted via email I'm gong to
recommend that the dsl business/dsl savings of around $1.5k per year
isn't worth the risk to the email service and the savings could easily be
taken up in support costs with another connection method.
We are going to set up a voip trial and see how it works.
