I have been approached by a number of small customers 3-10 phones for quotes but the IPO just isn't a good fit for businesses that small so I am considering setting up a hosted solution.
To avoid a lot of headaches I want to sell this into the same footprint as my local cable provider (Charter) that offers high-speed Internet, including fiber connections and SIP trunks. I would only sell to customers that had the same Internet service and I would have a fiber connection (50/50Mbs)at my end while the customers would have copper at (60/5Mbs). This should avoid a lot of problems with latency, congestion, jitter, etc...
I would like to use the IPO because then I can sell the hosted solution with a future option to convert hosted customers to premise customers as they grow or as the need arises and they can just keep the same phones. This would make it a safe bet for the customer to go hosted. I think I would have to have a site-to-site VPN with each customer which I don't like but I don't think it would work too well any other way with the IPO. Using the IPO would also give me the opportunity to sell value-added apps like call-accounting, call-recording and call-center that would never be feasible otherwise in a small office. It is difficult enough to just keep all that going straight with the IPO and I don't really want to become an expert on a whole other solution. There are obviously trade-offs.
I'm not looking to be the PBX vendor for the whole world, just my local area.
