Polycom Vega Gateway appendix User experience

Page 21

•Consider VPN between sites as this:

-removes any issues with firewalls / NAT

-encrypts audio and management data

•Vega gateways use the ECMA 333 standard for tunnelling QSIG

User experience

•There is no change to the existing user experience. The information provided between PBXs is identical, so the PBXs see no change at all.

•The user experience is defined only by the PBX capabilities.

USPs

•QSIG signalling and QSIG-like signalling are supported by the Vega

Considerations

•Point-to-point trunking1 rather than fully meshed2 connection of Vega gateways may be needed if:

-the protocol is QSIG-like and not fully QSIG compatible (some manufacturers use QSIG as a basis for their inter-PBX connectivity, but retain certain proprietary elements)

-PBXs send calls for specific destination PBXs to specific trunks

•QSIG from different manufacturers may have proprietary elements. If QSIG PBXs would not talk together when connected with a leased line, they will not operate together when connected using VegaStream QSIG tunnelling.

Future extensions

3rd party product choices

•-

1‘point-to-point trunking’ means that all calls on a specific Vega trunk will be routed to a specific destination trunk on a specific destination Vega gateway

2‘fully meshed’ indicates that on a call by call basis the Vega gateway can select the appropriate IP endpoint to send the QSIG data to.

Vega Gateway specifications

Polycom Vega Gateway serves as a crucial component in modern telecommunications, bridging the gap between traditional telephony systems and Voice over IP (VoIP) networks. As organizations transition to digital communication solutions, the Vega Gateway plays a vital role in ensuring compatibility and enhancing connectivity.

One of the primary features of the Polycom Vega Gateway is its ability to facilitate seamless interoperability between different communication protocols. It supports a range of signaling protocols, including SIP (Session Initiation Protocol), H.323, and analog interfaces, making it easy to connect legacy phone systems to modern VoIP setups. This flexibility allows businesses to gradually upgrade their telecommunications infrastructure without the need for costly complete system overhauls.

The Vega Gateway is equipped with advanced transcoding capabilities, which enable the conversion of audio streams between various formats. This is especially beneficial in multi-vendor environments where different systems may use incompatible codecs. Its ability to transcode ensures high-quality voice communication regardless of the underlying technology, thus maintaining clarity and reducing latency.

In terms of deployment, the Polycom Vega Gateway can be implemented as both a hardware appliance and a virtualized solution, providing businesses with deployment flexibility based on their IT environment. This adaptability is crucial for organizations looking to optimize their resources and scale their telephony solutions as needed.

Security is another key characteristic of the Vega Gateway. It incorporates robust encryption protocols, such as SRTP (Secure Real-time Transport Protocol), to safeguard voice communications against potential threats. Additionally, the gateway features firewall traversal capabilities, making it suitable for deployment in various network environments without compromising on security.

The gateway is also designed with ease of management in mind. Administrators can configure and monitor the device through a web-based interface or command line, ensuring that managing the system remains straightforward even for complex setups. Logging and reporting functionalities further enhance administrative oversight, allowing organizations to analyze their VoIP usage and optimize resource allocation.

Overall, the Polycom Vega Gateway is a comprehensive solution that addresses the complexities of integrating modern VoIP technology with legacy systems. With its robust feature set, diverse technological support, and commitment to security and manageability, the Vega Gateway stands out as an essential tool for organizations looking to enhance their communication strategies in an ever-evolving digital landscape.
