We're a VoIP provider in California with carrier arrangements for DIDs throughout much of the US. We have a few customers with offices in Canada and are beginning to get inquiries from others with cross-border US/Canadian presence. Has anyone gone down this path that can give some pointers? Obviously we can put IADs with FXO (or even PRI) ports on-premise at each customer location tied to the local telco but this doesn't scale all that well. I'm looking for legal/regulatory info about such things as taxes, 9-1-1, getting listed in the local white pages, etc. as well as any technical obstacles and recommended providers. Technically it appears to be pretty straightforward. It's all part of the same NANP. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
