voice over ip (VoIP)

IP Telephony is the technology for transmitting voice communications over a network using open-standards-based IP. Nashita IP Telephony solutions use a single network infrastructure for the transmission of data, voice, and video traffic, delivering the business benefits of a converged network (increased productivity, greater business flexibility, and reduced operational costs) for medium to enterprise-level organizations.

The advantages of VoIP over traditional telephony include:

• Unlike traditional telephony, VoIP innovation progresses at market rates rather than at the rates of the multilateral committee process of the International Telecommunications Union ( ITU).
• Lower costs per call, or even free calls, especially for long-distance calls.
• Lower infrastructure costs: once IP infrastructure is installed, little or no additional telephony infrastructure is needed.
• New advanced features.
• A higher degree of reliability and resilience.
• "Future proof" system upgrades, since the functionality is software (protocol) based and does not require hardware replacement.
• Voice over IP traffic does not necessarily have to travel over the global Internet; it may also be deployed on private IP networks for example on a LAN inside a single building.

• Infrastructure
  Includes public switched telephone network (PSTN) gateways, analog phone support, and digital signal processor (DSP) farms. Nashita IP Telephony infrastructure solutions can support multiple client types such as hardware phones, software phones, and video devices, as well as provide options for integrating traditional PBX, voice mail, and directory systems.
• IP Phones
  Nashita provide IP Phones from different manufactures. Our Cisco and Sipura IP phones combine the functions of a traditional telephone with an Ethernet connection and optional customizations such as access to stock quotes, employee extension numbers, and Web-based content.
• Voice Applications
  Voice applications are physically independent from the call processing and voice processing infrastructure, and they may reside anywhere within your network.
