Information notice:
Callcentric Wholesale, Inc. (a parent of Callcentric) owns and operates its own TDM/SS7 network interconnected with major (as well as small ones) carriers, networks and voice exchanges - over 800 interconnections, nationally and internationally directly from its switch in NY headquarters. We guarantee an optimal voice (media) path to most domestic and international destinations.
Callcentric Wholesale is also an ARIN registered ISP, operating its own IP network blocks and exchanging BGP-4 routing information with most ISP backbones (also nationally and internationally) via its own managed fiber optical network thus guarantying the best IP packet delivery to virtually anywhere in the world (we monitor such parameters as round-trip time, packet loss and number of hops to most international destinations and adjust our routing according, if/when required).
Our average and sustained round-trip time to: Hong Kong is 225ms while we're reaching Tokyo (Japan) in under 175ms. Sydney (Australia) is under 230ms; almost all European destinations are under 150ms (London - 75ms; Paris - 85ms, Berlin - 90ms); Israel - 120ms, Jordan - 120ms, Egypt - 120ms, Saudi Arabia - 120ms, Pakistan - 125ms, Kuwait - 140ms, most cities in India - under 150ms, Bangladesh - 200ms (Bangladeshi national fiber backbones are quite overloaded with no signs of expansion; satellite link under 850ms); Mexico - 115ms, Brazil - 135ms [Sao Paulo]; USA from NY to West coast - under 80ms, to Miami - 35ms; Canada to Toronto - 25ms, to Vancouver - 85ms (at worst, most of time - under 65ms). Big Apple, anywhere within 20 miles - under 10ms. Again, the above stats were round-trip - you don't need to multiple them by two )
We're NOT co-located with any providers - we operate our own data-center (with all underlying infrastructure, under 24x7 video surveillance) with redundant air-conditioning and AC power-plants; our dual-redundant AC sources reside on the same AC power grid with NY stock exchange (which is just across Broadway from us). In fact, we provide co-location, IP and TDM connection as well as origination and termination services to many international operators. |
