Yeah, I suppose RAD being the first with TDMoIP, have to recoup their R&D costs. Their products work as advertised though.
Recently, we were involved with a couple of customers who moved to TDMoIP using 2 different products from
Actelis as the CPE. One was a straightforward T1-over-IP box, the other though was more interesting, it was acting basically as a remote LAN switch that could emulate all kinds of circuits at symmetric speeds of 45mb/second over regular copper wire at up to 3000 feet, or 50000 feet with repeaters (!). The "telco" has master layer 3 switches at the CO establishing point-to-point VLAN-based connections. This box can also establish "dynamic" T1 services, where the voice channels become data when not in use (and vice-versa). No PRI with dynamic T1 though.
The price blows "traditional" T1 out the water. The customer gets T1 speed and quality, and T1 SLAs from the provider. What do they care how the signal comes in?
[Edit: put in the correct distances]
