[COLUG] Business net access in Dublin

[Vallance, Noel]

Dave,
I don't have any experience with VOIP over DSL but latency and class of
service are your friends.
If you can set the phone system to only use a specific DSL lines you can
pay for the premium services only on that line.
You could also try pricing a frac T1 and a DSL line.  Prioritizing your
voip over the T1 and falling back to the DSL when the circuit gets full.
Time Warner Communications has been expanding their fiber and pushing
their Ethernet solutions for the last several years.  If they already
have fiber in the building or if the client has a long term lease on the
building to recoup install costs it might be worth while.  You'll still
want to setup X amount of prioritized bandwidth in the service contract
for voip or else you run the risk of poor or dropped calls.

Subject: [COLUG] Business net access in Dublin

I've got a client who's expanding his business in Dublin.  The office is
in 
Tuller Park Road pretty close to the Target.

They've hit the wall with Business Class RoadRunner.   As soon as the
kids get 
home and fire up their P2P clients and hit their MySpace pages, they
become 
unable to reliably recieve faxes or make calls over their IP phones.

The problem is bad enough that I set up a Hylafax server for them at
another 
site (fun fun in itself!).

They are currently mulling two options.   AT&T will sell them either
three 
768K DSL lines or 1 T1 and a set of fixed IPs.  Without a doubt, the DSL

lines will have waaaayyy more bandwidth but they absolutely need
reliable IP 
telephony.  And it is a case of install 1 or the other.

Anybody familiar with the business class DSL service there?  Can you run
IP 
telephony over it OK? Are there other options?

I really didn't have an answer for him but told him that apart from the 
obscene amount of money for the T1 that the DSL would be faster overall
but 
that he may need the T1 to get closer to some sort of guarenteed latency
for 
his fax/phones.

Thanks

Dave
