An ip telephone system is a full blown telephony platform that offers phone calls over IP networks. All voice communication is transmitted as data packets across the network using digital protocols. The latest technology has a significant dose of redundancy and robustness, but offers limited scalability. This limits the system to certain applications, while drastically increasing the ease of deployment.
Most people familiar with internet telephony have little to no experience with IP telephones. These telephones work much like traditional phones, except they use an internet-based protocol (SIP) for the back end. The SIP, or Simple Internet Protocol, is a generic standard that allows any computer to communicate with any IP-enabled computer. The packets contain data that can include caller ID, phone number, and so forth. Calls are placed on the same server as webpages and audio or video content, so the data can be routed in the same fashion as a website.
A typical sip based IP telephone system allows one-to-one communication between a number of IP phones and a single IP-enabled phone line. Businesses which operate globally need to implement this technology since international phone lines are rarely available. This type of ip pbx system allows employees to connect their telephones to their laptops or desktop computers from any location in the world. The system provides redundant power sources and power saving options to help minimize energy costs.
Business systems often offer more functionality than simple voice mail or STD/ISD services. Calls between multiple numbers can be managed from a central control station using the SIP system's centralized dialer. This feature allows you to route calls to employees based on their user names, which improves productivity and efficiency. Also, call forwarding and call waiting can be implemented, which helps you make use of the toll free numbers for your traditional phones, and routes calls from these numbers to your ip phone lines when you have employees that have connecting international calling cards. This feature also allows you to utilize your voicemail and e-mail forwarding features for business phone calls.
Some businesses, such as call centers, may be better served by an IP telephone systems. These systems usually allow multiple users to connect to the same phones at the same time. Callers are able to dial multiple numbers and enter their unique codes to connect to other callers. Caller identification is also available, which gives users the opportunity to see who is trying to call them.
All of the features that are offered by an IP telephone systems can also be applied to voicemail programs. voicemail programs allow a business or private individual to schedule an automatic email delivery service. Users can set up their own account, where they can schedule the delivery of their voicemail at specific times. This service provider will then deliver all messages in the inbox on the designated date and time. This post: https://en.wikipedia.org/wiki/IP_PBX will help you understand the topic even better.
