IP Network

•Recommend – private IP network between sites

•Can be any reliable IP connection, including leased line, line of site laser / wireless connection and satellite

•QOS should be implemented to ensure that VoIP packets pass through the network in a consistent and timely manner and are not discarded by congested routers

•Consider VPN between sites as this:

-removes any issues with firewalls / NAT

-encrypts audio and management data

•A VPN can be used from the home user to the company LAN. This is important for securing data access to the company site, and for VoIP it gets around NAT traversal issues

User experience

•The user experience will be completely controlled by the SIP proxy / H.323 gatekeeper. Choice of the correct application server device will be key to successful delivery of service.

USPs

•Vega gateways are very good at interoperating with 3rd party VoIP devices.

•Features available that are not available on traditional telephony

Considerations

•Check that the data network is capable of supporting VoIP (QoS / bandwidth)

•Where a media server is used, consider placing it close to where the media is going to be used – this minimises the distance over which ‘fat data pipes’ are needed to route audio traffic.

Future extensions

•Connection to an ITSP for cheaper off-net calls – and possibly for more flexible ingress of national, international or non-geographic numbers.

3rd party product choices

•PBX: Snom

•Intelligent Call Routing: Rostrvm, Teleware, Alceo, Interactive intelligence

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.
