We currently have our business calling and internet with Vodafone. Due to price and the way we use our phones, we are currently investigating a move to a VOIP solution with naked DSL. We have considered the potential downsides of a VOIP connection, but have decided the cost savings and additional functionality (PABX-lite) is worth the risks, particularly given that landlines are not 100% mission critical for business.

I have spent quite a bit of time testing 2talk's VOIP offering, and are very pleased with the call quality and functionality.

While we are in Wellington, the odd position of our building means that we are not able to get Telstra cable, so unfortunately need to stick with ADSL.

My question is what is the best way of transferring over? Do I shift the internet first, or do I port the phone numbers? If I port the phone number, I am guessing that I will also cancel the existing internet (the internet is attached to the main number I want to port)? But if I transfer the internet across to a naked DSL plan, then that will also cancel the phone number won't it?

So basically which do I transfer first?

I have looked at other providers that offer both a VOIP and naked DSL plan. But most seem to fall down on one aspect or other of service (thanks Geekzone!), so I was thinking that if I go with dedicated providers for the various services and I am not happy, I can ditch just that one without having to go through this exercise again. But this may be more trouble than its worth?
