The development, engineering, wiring up and maintenance of corporate telephony systems
Oss-it integrates the systems of IP-telephony based on the Asterisk server. Depending on the specific requirements of our customers, the subscribers of a corporate telephony system can be connected across a local network, or over the Internet.
As a result, each subscriber gains access to virtual conference rooms and becomes exposed to other benefits of IP-telephony, such as the call transfer, automatic redial, voice mail, voice menu, and other services.
The IP-telephony (i.e., the transfer of voice via computer networks) costs considerably lower than a traditional telecommunication performed by using a telephone cable. The two main ways to implement an IP-telephony are as follows.
1. The first approach is to install a telephony software (requires connecting a set of headphones and a microphone to the computer) or a digital SIP-telephone (a separate device connected to a USB port) that can reach out to the operator’s server via the Internet (e.g., via Skype, Gizmo or a regional SIP-provider). These operators typically charge far lesser fees than traditional telecommunication companies, especially when it comes to international and long-distance calls. We can help you select an optimal implementation of an internal digital telephone network that bests meets your specific requirements.
2. The second approach is to afford a dedicated SIP-server connected to an analog ATX (automatic telephone station). This enables a customer to enjoy all advantages of IP-telephony while securing a direct access to the existing urban telephone networks. As a result, the call operators (e.g., a secretary or assigned executives) are no longer tied to any specific location and can answer and transfer calls from any computer connected to the Internet.
Moreover, you can come into possession of a local or federal phone number that can also be answered from a distance (e.g., by the employees of a remote office located at the other hemisphere, or by yourself via a mobile phone or tablet).
To sum up, the IP-telephony is a remarkably effective solution to any business communication performed by means of fixed telephone lines.
The above image illustrates a configuration that is typical to IP-telephony: the server receives the calls from the ATX and uses external SIP-providers to cut the international and long-distance traffic expenses, along with providing the mini-ATX functionality to IP-operators (headset-equipped computers and tablets, as well as SIP-telephones).
