SIP Trunking

What is SIP?

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.

What is SIP Trunking?

A SIP Trunk is a virtual phone line that utilizes a Broadband connection for access, offering up to 40% savings over traditional telephone lines, with benefits including:

  • Rapid Return On Investment: SIP Trunking is cost-efficient to implement and CAPEX negligent, meaning businesses can maintain their same previous features at a fraction of the cost overtime.

  • Fast Geographic Growth: SIP Trunking combines voice and data to better connect distant business systems, helping companies establish faster, wider geographic growth.

  • Reduced Call Costs: SIP Trunking can half your enterprise’s telecommunication budget due to reduced call costs for making and receiving calls—and since calls are made via IP connection, you won’t have to worry about long distance charges.

  • Enhanced Scalability: Unlike traditional POTs 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.

What is Shared SIP Trunking?

Shared SIP trunking is when more than one office shares SIP trunking services through one account. The benefits are many, and start with the customers ability to plan for peak concurrent call utilization across the enterprise, versus on a location by location basis. Most of the time this will result in immediate cost savings, as well as a more flexible and scalable solution for the customer.

Sample Customer Requirement

Let’s say that a customer has 3 locations. They currently have 15 lines (POTs lines, or call paths on a PRI) at location one, 10 lines at location two, and 5 lines at location three. That’s 30 lines total today (15 + 10 + 5 = 30).

Solution

Customer can have one or many SIP trunk groups, and any number of pre-paid call paths. Also they can have the ability to “burst” up to ten (10) additional call paths on-demand for a slight surcharge.

In many cases, customers can make due with 20% less (or more) lines if they could be shared across the enterprise. So instead of 30 lines, they may only need 24 lines (30 x .8 = 24). Not only is that an immediate cost savings, but there are call routing and business continuity benefits included with the service.

Benefits

  • Burstability – ability to burst above the number of pre-paid trunks or call paths on-demand (i.e. automatically).
  • Control – make changes to the customers configuration on-demand, and as needed.
  • Advanced call routing – provide the customer with the advanced routing capabilities in our cloud software platform.
  • Business continuity (Enhanced SIP trunking) – Configure a SIP trunk to automatically failover to another location, cell phones, or any number of other scenarios, without manual intervention. If your PBX hardware fails, or you lose power, your customers can still call and reach you.
