If he hosted the softswitch and all his sites connected via Speakeasy then they would sound better - since the traffic would most likely never leave Speakeasy for the cloud - but they would not have QoS applied for their traffic (unless they were going directly to Speakeasy's softswitches), so while the voice would probably sound good it wouldn't sound as clear as going with a hosted solution. The best solution (if he hosts the Softswitch directly) is to have a dedicated line from one ISP that feeds the VoIP traffic to the softswitch, and then use a separate ISP for internet access. We run some Soho clients this way. They have DSL for their data needs and use TW for their VoIP connections. We do it this way because VoIP never uses enough bandwidth to cause any restrictions (Bandwidth queueing that is) on the head cable router - so the latencies stay within a nice range. The latencies on a DSL connection from Bell are very unpredictable - even when there is no load. Verzion's DSL is generally better. Sprint's seems to cycle from okay to horrible, leading me to believe that they have absolutely no management on their network access points. Speakeasy does a really good job - much better than TimeWarner. Unfortunately they aren't available everywhere - and some places where they have a presence they aren't accepting any new customers - so they don't overload their networks (what a concept!).
