Hi,

Been looking for something similar to Italk where there are cheaper national and international rates and that it can accept calls.

I assume it uses SIP.

Anyway was looking to find some user reviews/opinions about the service, any recommendations for alternatives and so on.

I was thinking of getting Asterisk PBX and running on the service as well as I have a linux box sitting in my flat doing nothing much.

I have Asterisk installed at home and have both an iTalk account and an Australian MyNetFone account. This gives me cheap phone calls inside NZ and also A10c untimed calls anywhere in Australia as well as an 09 and a Melbourne local number.

The iTalk service itself is rock solid and I can't fault it - on a cable modem connenction. The problems start happening when you try and deploy VoIP over ADSL connections. Some people are having no trouble and others huge problems primarily over UBS connections due to the higher latency and the packet interleaving that Telecom have deployed.

Ideally you want to be using u.law as your voice codec, this uses roughly 174kbps (87kbps both upstream and downstream). This gives you ISDN voice quality and is actually better than a standard phone call. iTalk recommend using g.729 which uses far less bandwidth but the quality is not as good (you could probably compare it to a cellphone call) however over ADSL it's probably the better option.

GoTalk is also another option for the NZ market appearing very shortly. I saw VoIP routers at Harvey Norman the other day with big GoTalk stickers mentioning www.gotalk.co.nz however this site is dead. www.gotalk.com.au is live however.
