HI Guys, I was wondering somebody can shed some lights on the following questions.
Suppose I'd like to start a business, like, Vonage, iTalkbb, unlimitel, etc. VOIP ITSP and provide many customers with DIDs. 1. Where do I go to get those DIDs? Is it from Bell, Allstream, Rogers, or CRTC? 2. What's the best approach for customer to receive call from PSTN and call PSTN? Do I set up a T1 link with Bell, Allstream, Rogers? or Do I set up a SIP trunk with Bell, Rogers, Unlimitel? 3. How to use ENUM or SIPbroker with this? It seems interesting to have all PSTN number (owner has some voip box) registered in e164.org and those call between can bypass PSTN from one ITSP to another ITSP. isn't this beautiful for users as well as ITSP? Does unlimitel.ca, vonage, etc support this? It should be a free call between ENUM registered users and not paying any $$ to PSTN and ITSP. The same goes to sipbroker. Just try to gather some ideas. thanks in advance. Peng
