Help Maximize Network Capacity with SIP Trunking
Businesses are trying to improve the ROI of voice services. They want to get more from existing PBX system investments while continuing to support premium voice services.
Session Initiated Protocol (SIP) Trunking is one method of converging voice and data. It can help improve efficiency by maximizing the use of network capacity.
Improve networking ROI with SIP Trunking
Discover how implementing SIP Trunking with AT&T Flexible Reach helps Kaman provide uninterrupted customer service with operational efficiency.
SIP Trunking can help improve your ROI in several ways:
- Leveraging unused bandwidth. With voice and data converged on one network, bandwidth can be dynamically allocated to allow for increased or decreased usage in either direction. For example, you can temporarily allocate bandwidth to support batch jobs during down times to reduce excess, idle capacity.
- Maximizing existing investments. SIP Trunking can support existing on-premises equipment.
- Consolidating resources. Converging voice and data on the same network means there’s no need to manage or pay for separate access.
- Increasing traffic. SIP Trunking uses compression technology to pump more voice traffic on the same size pipe.
Respond to dynamic needs using SIP Trunks
Whether you are announcing a new product or gearing up for a busy holiday season, your network needs to be able handle changing call volumes. SIP Trunking helps enable you to quickly adapt to dynamic business needs. It affords the ability to manage and adjust your voice services in response to changing demands, by:
SIP trunking is a logical first step for voice and data convergence, because the barriers to adoption are low, and the ability to gain efficiency is high.
- Providing the capability to add capacity without adding expensive T1 lines by dynamically allocating bandwidth
- Affording your customers a consistent experience with centralized call delivery features, which allow you to route calls from various locations and answer them centrally
Deliver new network capabilities
SIP Trunking creates an IP WAN connection that delivers unified communications capabilities, such as IP conferencing, unified messaging, instant messaging and "presence". It provides access to other new applications on IP communications servers such as Microsoft® Office Communications Server 2007 R2.Learn more about the AT&T SIP Trunking solution, AT&T IP Flexible Reach [PDF, 1Mb], Voice Transformation and other AT&T VoIP services.
Considerations for a SIP Solution
If you're considering a SIP Trunking solution, here are a few things to think about and discuss with your AT&T rep:
Do you need a VPN?*
Do you need toll-free service?
SIP Trunking works with AT&T IP Toll-Free to simplify contact methods with a single IP Toll-Free 800 number, helping contact centers and help desks operate more efficiently.
Do you have an existing key system infrastructure?
AT&T can deploy an AT&T managed router than includes a fully configured eight port Analog Telephone Adaptor (ATA) that lets you migrate to a VoIP infrastructure at your own pace. This router transports both voice and data traffic over the IP network. In addition, if outbound survivability is required, this device allows for alternate access to the Public Switched Telephone Network (PSTN) in case of a WAN failure.
Does your existing equipment need to be changed?
Most SIP Trunking customers keep their own phone equipment and its associated features. If you choose not to have a PBX and would like AT&T to manage your system, our Hosted VoIP option, AT&T Voice DNA®, may be a good solution.
Will virtual telephone numbers (VTNs) be needed?
SIP Trunking supports VTNs, which let you assign telephone numbers from your desired area code to any end-user, regardless of where the actual phone or person is physically located.*
Do branch offices need to be supported?
The Branch Office IP PBX Extension uses a single centralized PBX IP system to deliver telephone numbers for all your branch office sites without requiring additional hardware.
Do you need a simple configuration for a satellite office?
AT&T can simplify the installation of voice services in a satellite office with our fully managed Business in a Box service that provides a "single" consolidated device for the convergence of voice and data networks.
AT&T experts will work closely to help you plan, design and configure the optimal SIP Trunking solution for your business. We'll use a checklist to help uncover all your needs and design a total solution that includes the various services you need.
