SIP Trunking for Telecom Service Providers

As a telecommunications service provider, running your business on a tight budget in today’s tough economic environment makes clear the importance of investing in switching platforms that are capable of delivering Next Generation Network services quickly and cost effectively. The current economy has reaffirmed the need to minimize your telecom spend and maximize your return on capital expenditures. SIP trunking via REDCOM’s TRANSip® technology suite with either a REDCOM HDX or SLICE® 2100™ Carrier Class 4/5 softswitch is a powerful way to build your business in these uncertain financial times.

SIP trunking is a secure, cost-effective way for service providers to leverage their IP network to provide voice service. SIP trunks deliver a significant return on investment and TRANSip-equipped HDX and SLICE 2100 softswitches have extensive SIP trunking capabilities to ensure that your switching resources fit your business model for current and future growth.

Benefits of SIP Trunking for Service Providers:

  • Higher margins due to reduced install/configuration time
  • Simplification of value-added services
  • More services delivered over same pipe
  • Expansion into additional markets
  • Powerful bandwidth control/savings
  • Support for wide variety of codecs as well as T.38 and V.150.1

What is SIP?

SIP is a signaling protocol that assists in originating, managing, and terminating VoIP telephone calls and represents a complete break with traditional telephony protocols. It is a generalized protocol for allowing “user agent” clients and servers to associate, and when communication is desired it allows them to exchange capabilities, make media choices and finally establish communication sessions between them.

Why SIP Trunks?

As your business grows, the extensive SIP trunking capabilities of REDCOM’s TRANSip technology suite allows you to scale your telecom system faster and more cost-effectively than with traditional phone lines. SIP trunks are used to connect two switches together. As long as each switch has an IP address, communication can be made from one point to the other. With proper network assessment planning and implementation, SIP trunks can deliver high quality and reliable service with substantial cost savings that directly impact your bottom line.

SIP trunking represents a tremendous opportunity for service providers to implement advanced telephony applications at a lower cost than ever before. As your business grows, you are well-positioned to rapidly create and deliver new revenue-generating services. Migrating to VoIP is easy with either the TRANSip-equipped REDCOM HDX or SLICE 2100, which works seamlessly with your current infrastructure to convert your existing customers to IP customers.

Why TRANSip?

The REDCOM HDX and SLICE 2100 with the TRANSip suite supports both your IP telephony and circuit-based telephony needs. In addition to supporting TDM to TDM calls, REDCOM’s breakthrough TRANSip technology permits IP to IP, IP to TDM and TDM to IP calls. All TRANSip-powered HDX and SLICE 2100 systems include the Media Service Circuit (MSC) board, which acts as a Media Gateway bridging the gap between traditional TDM networks and VoIP networks. The SLICE 2100 has a fixed configuration with a single MSC board; the HDX is expandable and can accommodate multiple MSC boards.

TRANSip also utilizes a Controller board in the HDX and SLICE 2100 for SIP signaling. This board provides PCM clocking, communicates with other systems on an IP network, and controls the administrative functions such as setup, connection and feature selection.

All that is required is a TRANSip-equipped HDX or SLICE ® 2100 softswitch with a SIP Call Controller, and an IP network, and you will be on your way to implementing SIP trunking. In addition, the HDX with TRANSip supports up to 3,000 registered IP subscribers per shelf (2,000 per unit in the SLICE 2100). REDCOM does not require you to purchase IP registrants for either the HDX or SLICE 2100, allowing you to add these later in order to minimize the initial investment.

SIP Trunking: An Easy Choice

It’s no surprise that more and more service providers are turning to SIP trunking to secure tangible cost savings and to enhance their service offerings. The rapid return on investment and increased network efficiencies that come from SIP trunking make the decision to adopt this approach an easy one for many service providers. With the extensive SIP trunking capabilities of REDCOM’s TRANSip-powered HDX and SLICE 2100 softswitches, service providers are able to reduce or terminate altogether their use of expensive BRIs, PRIs, and other legacy circuits, and thereby reduce costly telecom expenses and their Total Cost of Ownership (TCO).
