You can extend your corporate office VoIP services over the internet to any location using VPN.

Well.. good luck. Remember that voice is a dely and packet-loss sensative medium. VOIP is fine over PTP T1s, but even MLPS networks have issues when the providers are 'guaranteeing' you priority and <1% packet loss. As far as hosting a real VOIP trunk over the internet to another continant, you would probably experience so much jitter and chopping it would be more frustrating than anything.


On the other hand there are 'internet phone' providers such as Vonage... I do believe they have business services that would be condusive to your needs. Your calls would be going across their PTP trunks, but as far as priority and packet loss, still not guaranteed outside their network. But you still do have a phone bill at the end of the day.

So, if you have a PTP data infrastructure you would like to leverage to run your international calls over, very do-able.

As stated above.

Keep a constant VPN state and you'll be able to address them via your VPN.

Most VoIP consist of a 20ms jitter which covers almost any problems. I've been using VoIP calling across the US and over to Europe without a problem.
