With a TP call using a CTS3000, you're entrusting a throughput of up to 18Mbps to the network. You simply can't trust the internet to give you that sort of throughput with no jitter or packet loss, so the call experience will be poor.
Also with the CTS3000, it is likely that your users will not be very forgiving of bad call quality degradation after spending hundreds of thousands of dollars on a system like that.
That's why placing TP on a network where you know that the bandwidth is guaranteed and delivered with a Service Level Agreement is really important.
we couldn't able to spend 1,000,000$ per year for a direct link to TP Provider to give us service when the Top management need TP Meeting with partners in Canada ,London ,USA, and ME,so we think for a chipper solution for that matter
It's entirely possible to use the internet as a transit network, just don't expect any sort of quality of service or service level agreement
Also, the risks get higher, the higher up the endpoint ladder you go. The CTS3000 is the top-end TP solution costing hundreds of thousands of dollars, and is designed to give a premium experience. In my experience of working on these solutions, Cisco and a reputable partner wouldn't allow you to put one of these systems on the internet just because the Internet isn't fit for purpose for those systems.
However, if you bought an SX20 with a 65" screen, you can just as easily hold a 'TP style' meeting for much lower cost, just don't expect the premium experience as the internet is totally unpredictable that way.
You should also look at VCS expressway for Firewall traversal if you are lookig to use the internet as your transit network, as it's very likely your traffic will need to traversal firewalls.
we are based in Jordan ME , our Partners at Canada ,London ,USA, we have got an offer from a TP Provider with direct link (10XE1) but the cost will be 1,200,000$ on yearly basis ,we can't afford this Price that's why we think to run the services over the Internet ,as y know 1,200,000 $ its costy
