Why should I consider SIP Trunking?

Rapid Return on Investment (ROI)


SIP Trunking is cost-efficient to implement and CAPEX negligent, meaning your business can maintain the current features at a fraction of the cost overtime. 

Fast Geographic Growth


 SIP Trunking combines voice and data to better connect distant business systems or multi-site operations, helping companies establish faster, wider geographic growth. 

Enhanced Scalability


 Unlike traditional PSTN (telephone company lines) and T1/ PRI lines that require planning for peak call times, SIP Trunking offers the flexibility of on-demand scalability, meaning it can scale up or down as your business needs it. 

Reduced Call Costs


 SIP Trunking can cut your enterprise’s telecommunication budget by half due to reduced call costs since calls are made via IP connection and you won’t have to worry about long distance charges. International Long distance service typically costs significantly less with a SIP trunk connection. 

Eliminate IP-PSTN gateways or even your entire PBX


 Because SIP Trunks connect directly to Voradian’s Telephony Platform without traversing the publicly switched telephone network, you can get rid of IP-PSTN gateways and their attendant cost and complexity. Moreover, we can even host a PBX for you, taking over both the PBX hardware and user administration if you choose, with substantial cost savings from reduced complexity, maintenance, and administration. 

Eliminate a redundant network


Deploying SIP Trunking is a logical step towards the goal of having a single, IP-based network, rather than redundant telephone and data networks. 

Eliminate BRI (Basic Rate Interface) and PRI (Primary Rate Interface) subscription fees


With a SIP Trunk connected directly to Voradian, you can dispense with costly BRIs and PRIs, replacing them with service that can cost significantly less. Furthermore, with SIP Trunking you don’t need to buy lines in blocks of 24 or 32 such as T1. Instead, you can buy the bandwidth you need in smaller increments, and at better prices. 

Extend the capabilities of Office Communications Server with new services from Voradian


 With a SIP Trunk in place, you can extend existing capabilities with additional services, such as E9-1-1 emergency calling. In addition, you will have greater integration capabilities with mobile phones, presence information on devices, and the ability to add enhanced communications capabilities with Unified Communications and Collaboration tools from Voradian or any other compatible third party solutions.  


Session Initiation Protocol (SIP) has become the common signaling standard for real-time communications for Voice over Internet Protocol (VoIP). SIP is an open-standard, which enables our customers to seamlessly connect existing Customer Premise Equipment (CPE) with our carrier class voice network. SIP trunk is a direct connection between your organization and Voradian’s Internet Telephony Service Platform. Our SIP solutions enables you to extend VoIP telephony beyond your organization’s firewall without the need for an IP-PSTN (Internet Protocol –to- Public Switch Telephone Network) gateway. In addition to voice calls, our SIP trunks can carry instant messages, multimedia conferences, user presence information, Enhanced “911” (E9-1-1) emergency calls, and other SIP-based real-time communications services that traditional phone company services are unable to do.
