What is Voice over IP?
Voice over Internet Protocol, or IP telephony, is a technology that enables you to make ordinary telephone calls over a computer network or the Internet. An IP system converts the voice transmitted over your telephone into digital signals and sends these signals in data packets over the Internet. It then converts them back on the other end, allowing you to speak to virtually anyone with a telephone.
Today, companies use VoIP technology to reduce or eliminate long-distance costs, include remote or home-based employees on their enterprise calling systems, or enable these remote employees to retain a company extension as if they were working on-site.

Survivability
Peace of mind via a back-up system—survivability and redundancy for IP Telephones
Today’s business environments place heavy demands on PCs, firewalls, printers, and especially your telephone system. Enjoy the benefits and security of knowing that, with Toshiba’s Survivability solutions, your IP telephones will continue to operate 24/7. The Toshiba Strata® CIX™ has the ability to automatically re-register to a secondary system if the primary system fails. Plus, survivability is scalable from one IP telephone to some or to all the IP telephones in the primary system. Choose survivability for key individuals, specific departments, or all users within the system. Even voice mail will continue to operate on the Media Application Server (MAS), automatically reconnecting to either system when it becomes operational again. Learn more about survivability.
Trunk-side VoIP
SIP Trunking
AT&T now offers IP Flexible Reach, a SIP Trunking solution.
SIP Trunking delivers fully integrated access for customer IP systems with true “all distance” calling – local, long distance, and international voice and data on a single network. SIP Trunking can be provided via the system IP card, PRI card, or analog line interface.
How It Works
The system communicates natively with a service provider over an IP circuit, carrying voice and data simultaneously. Voice is converted to data and sent along with the same circuit as the other data packets. Data gets entire bandwidth when no voice is present. Quality of Service (QoS) is managed by the service provider, with voice taking priority over data.
The IP Flexible Reach product is a different type of product than your current dial tone. Instead of lines coming in on rollover, IP Flex provides concurrent calls that are dynamically allocated based on usage.
It also provides:
- D.I.D. (Direct Inward Dial) numbers
- Virtual Numbers – phone numbers for any city where AT&T supports IP Flex Reach that will ring into your system as “local calls”
- Long distance savings
- High-speed data with dynamic bandwidth (guaranteed base speeds)
- Integrated router with handling routing of voice and data to your IP network
- Monthly savings
- Access to Business Direct for servicing, bill access, reporting, and tools
