<div>Hi -- I have a question part business, part architecture. (and I am kind of newbie in this field...)</div>
<div> </div>
<div>I am working with a company that want to expand their line of products and enter the hosted PBX market. They want to develop a special PBX application/IVR for a vertical market, and they will host it.</div>
<div>They plan on using Asterisk -- having the server being SIP only (no FXO/FXS card). </div>
<div> </div>
<div>As a PBX hosting, they also need to provide phone numbers, and access for PSTN (for incoming calls and outgoing calls to their customers). </div>
<div>So they are looking for a VOIP company that can provide this. Looking at various VOIP comapnies in the US -- I have a hard time filtering out the various services provided by these companies, and understand exactly who is providing what.
</div>
<div>We need </div>
<ul>
<li>the ability to order DID (on behalf of our customers), having them forward to the Asterisk server</li>
<li>Support for outgoing calls - made by our customers</li>
<li>A billing system that will allow us to correctly charge per customer. </li></ul>
<div>Obviously we dont want our customers to go to the VOIP company to pay/order for any service -- our hosting company should do this on their behalf.</div>
<div> </div>
<div>What VOIP company is providing this type of business. Any recommendation. </div>
<div><em></em> </div>
<div>Also, is there any recommend whitepaper/documentation about the PBX hosting business.</div>
<div> </div>
<div>Thanks,</div>
<div> </div>
