Carrier Services

We provide a number of Carrier Services, like SIP Trunking, PRI and WAN connections to ensure your IT infrastructure supports the flawless performance and QoS of your Unified Communications System.

Telecom carrier companies maintain their own network infrastructure to distribute large quantities of data over great distances. To make sure you get the best service possible on a local level (in your headquarters, remote sites, and mobile devices), your network must meet certain criteria and best practices.

SIP Trunking

SIP trunking is a voice over Internet Protocol (VoIP) technology and streaming media service based on the Session Initiation Protocol (SIP) by which Internet telephony service providers (ITSPs) deliver telephone services and unified communications to customers equipped with SIP-based private branch exchange (IP-PBX) and unified communications facilities. Most unified communications applications provide voice, video, and other streaming media applications such as desktop sharing, web conferencing, and shared whiteboard.

Having a reliable SIP Trunking provider is critical for the quality of your telephony services. According to SIP School's 2017 report, almost 37% of customers are unhappy with their current SIP Trunk provider. We are breaching this gap by providing an impeccable service and supporting our customers in every aspect of their Unified Communications system.


SIP Trunking enables advanced IP features to work across locations

  • Calls from your office phone can ring on your desk phone, mobile or simultaneously
  • All calls can be centrally handled for all locations
  • A single IP PBX can support users in multiple sites across the nation

SIP Trunking reduces costs by getting rid of idle capacity

  • SIP Trunking allows you to purchase fewer trunks at each location
  • Use idle capacity at one location to meet increased call activity at another location
  • SIP Trunking helps avoid wasting unused capacity at individual locations

    Primary Rate Interface (PRI)

    The PRI, or Primary Rate Interface, is a telecommunications interface standard used on an Integrated Services Digital Network (ISDN) for carrying multiple DS0 voice and data transmissions between the network and a user. PRI is the standard for providing telecommunication services to enterprises and offices. It is based on T-carrier (T1) transmission in the US and Canada with 23 voice channels and one data/control channel, which allows to hold 23 phone calls simultaneously.

    The PRI channels are typically used by medium to large enterprises with digital private branch exchange (PBX) telephone systems to provide digital access to the public switched telephone network (PSTN). The B-channels may be used flexibly and reassigned when necessary to meet special needs such as video conferences.


    Key characteristics of Primary Rate Interface (PRI) :

    • PRI is a physical connection to the PSTN over a dedicated line that only serves voice transmission
    • PRI uses a circuit switched model for making voice connections between people
    • PRI has a guaranteed Quality of Service (QoS)

      Wide Area Network (WAN)

      A wide area network (WAN) is a geographically distributed private telecommunications network that interconnects multiple local area networks (LANs). Business, education and government entities use wide area networks to relay data to staff, students, clients, buyers, and suppliers from various locations around the world. In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location.

      In an enterprise, a WAN may consist of connections to a company's headquarters, branch offices, colocation facilities, cloud services and other facilities. Enterprise WANs allow users to share access to applications, services, and other centrally located resources. This eliminates the need to install the same application server, firewall or other resources in multiple locations, for example.


      Types of WAN connections.

      WAN connections can include wired and wireless technologies.

      Wired WAN services can include:

      • multiprotocol label switching
      • T1s
      • Carrier Ethernet
      • Commercial broadband internet links

      Wireless WAN technologies can include:

      • Cellular data networks like 4G LTE
      • Public Wi-Fi
      • Satellite networks
