Network architecture

A solid network is at the core of any viable VoIP company. At iCall, we take our network architecture seriously.

Dallas network

We own and operate our own datacenter at our network hub in Dallas, TX.

To maintain our private peering and TDM circuits, we also maintain a presence in the Telx 2323 Bryan St. Meet Me Room in Dallas, one of the premier telecommunication hubs in the country. Located within feet of other major carriers such as Sprint, Verizon, and AT&T, we have pre-run fiber capacity in excess of 60 Gbps as well as unlimited TDM connectivity options. Our two Dallas POPs are connected via a redundant, protected fiber optic connection traversing two separate metro fiber rings.

Utilizing equipment from major vendors including Juniper routers and Cisco and HP switches, iCall maintains full network redundancy.

1505 Federal St. houses our core VoIP feature servers, customer colocation, and web servers. Our private cage space has ample capacity and power.

A private Layer 2 backhaul connects our NYC and Dallas POPs.

Our 60 Hudson POP consists of direct connectivity to Verizon, a private backhaul to Dallas, as well as public peering on the New York Internet Exchange. We utilize NEBS-compliant Sun Netra hardware and redundant A+B DC power plants.
