It works fine.

We started with VoIP in 99 buying from Selsius, the company Cisco bought.
Our early "Csico" phones had the Selsius badge on them. They worked fine.
We did investigate offering a VoIP service but walked away from it due to
the actions of the Commerce Commission and "the Deed".

We now use CallPlus Comverge.

However, I used to run a Cisco 8274V at home when the kids lived at home.
It was set up on the Cisco Call Manager at th eoffice and gave us 4 lines +
fax at home. It worked fine - other than the effect best described as
"early days of DSL with Telecom". We have full rate DSL 3meg down 700k up.

Based on our experience we set up an interoffice toll by pass for a Hutt
company. They have 3 827s as tie trunks on their PABX and call between WN,
AKL, CHC and now Brisbane, for around 1 cent a minute. Payback was 3 months.

I now use the Slingshot phones at home and in my van and they go fine. They
even work over my IPStar sat connex. The latency is a challenge but the
quality is great. Over DSL latency isn't an issue. If your pings are below
200ms you'll never know its voip. We learned that back in 1998 in tests
between US and NZ.
