Much of the PSTN is no longer a bunch of DSxs, but VoIP. Sure, anything connected to the tandem is DSx, but beyond that, little of it is aside from POTS.

I have spent the last 38 years working for the regulated side of the industry. So I am biased, however hard to argue against SS7/DS0 for speed and quality of connection. If it is G.711/DS0 full rate PCM from one end to the other there will not be jitter or latency. So that I way I want VLAN to SIP gateway that is connected to a regional tandem if I can get it. I can create this myself, I already have rack space, colocation, transport and connections. But there is no money in it for me to go to that work.

Explanation:- There are two legs to every call... one leg would be from the "switch" or "Proxy" to the Customer CPE, and the second leg would be from the "switch" or "Proxy" to the Voice Gateway (VOIP to TDM)... Making sure that the network connection is clean and of high quality on both legs will add to the quality, along with the Codec Conversion ... Making sure that the 2nd leg is of high quality network connection gets more challenging to do when terminating Nation Wide LD. VOIP / TDM Gateways are becoming less and less, since more and more the the Telco's are using Sonus Switches, thus keeping VOIP as packets end to end. Most of the larger public network connectivity on Fiber (as you pointed out) is of high quality and as long as it is congestion free it is just fine... In our experience, most of the voice issues tend to come from Codec Conversions (especially when they are done multiple times) and or High Jitter .... latency tends not to be an issue... (Packet loss can be a prevailing factor, but these days it is becoming more rare, unless you are traversing two IP Transit Providers who have over subscribed interconnection ports).

Better than using best-effort public routing to the gateway. But since everything is fiber these days and everything tends to work very well, it may not be a difference that would be noticeable.

Figure about $3-$4 per sub as a 'cost' of platform. $1 for DID + Caller ID lookup, and the rest would be used for mou's, I am assuming that taxes & fees along with E911 charges would be over and above the $7. At the end of the day it is going to be about Volume, i.e. 100 subs vs 1000 subs, somewhere about $2500-3k/month spending the balance between doing the flat rate style arrangement vs taking the risk on mou arbitrage will start to change. In regards to a 'local' provider, vlan providing quality would not be accurate, and quite possibly a myth. It only would address a very small portion of the actual path.. The quality greatly depends on the providers setup, i.e. how many codec conversions are taking place in the Voice path, and what is the network connectivity to the VOIP to TDM gateway or Sonus/ACME Switch path looks like. Folks commonly mistake in looking at the network path to the Proxy, or the call control data path, while the actual quality of the Voice is dependent on the network path of the Voice traffic, which is not the same as the call control traffic. It has taken a long time to learn the intricacies of VOIP, what affects it and how to identify them. We will be more than happy to work with you on this project of that makes sense.
