Hi Guys, I am looking for some more information so that I can get my head around the whole voip concept, namely infrastructure from the voip handset to the person on the pstn line at the other end.
the main part that I am having trouble with is; taking the digital internet traffic and passing it into the telecom pstn network.
At the moment - I am looking to move to voip in Whangarei, currently the only DID's that can be provided to me are from Auckland, which would mean people trying to call me would have to call an auckland number... to get me in whangarei and then pay telecoms charge for that.
What infrastructure is needed in the exchange here in Whangarei to enable me to get a local DID? Someone said something about an ISDN router.
If someone could point me in the direction of some useful docmentation regarding how it all fits together that would be very helpful. I am a network administrator so I have some understanding of how it might fit together but am lost as far as what gear is required to connect to the digital internet traffic to the exchange etc.
