VoIP: Telephone Over The Internet
One of the latest trends in PBX development is the VoIP PBX, also known as IPBX, which uses the Internet Protocol to carry calls that are feature rich and economical.
Businesses, Government Offices, Schools, and Home Users switch to VoIP to save money, receive better communications, and utilize a rich set of telephone features. LOD engineers provide “round-the-clock” VoIP support for the entire telephony system, including:
PBX (Asterisk, Trixbox, FreePBX, Broadsoft)
SIP Switches (OpenSER, Kamailio, OpenSIPS)
QOS (Network evaluation and engineering)
Phone Issues (Polycom, Cisco, Linksys, Aastra)
Planning and Deployment
VoIP can be a significant benefit in reducing communication and infrastructure costs, by:
Routing phone calls over existing data networks to avoid the need for separate voice and data networks;
Conference calling, IVR, call forwarding, automatic redial, and caller ID features that traditional telecommunication companies (telcos) normally charge extra for are available free of charge from open source VoIP implementations such as those offered by LOD;
Telephone costs are significantly lower, mainly because of the way Internet access is billed compared to regular telephone calls. While regular telephone calls are billed by the minute or second, VoIP calls are billed by the megabyte (MB). As such, VoIP calls are billed by the amount of information (data) sent over the Internet and not by the amount of time connected to the telephone network;
In practice the amount charged for the data transferred in a given period is far less than that charged for the amount of time connected on a regular telephone line.
VoIP can provide services that are often more difficult to implement using a conventional phone system, such as:
The ability to transmit more than one telephone call over a single broadband connection without the need to add extra lines;
Secure calls using standardized protocols (such as Secure Real-time Transport Protocol). Most of the difficulties of creating a secure telephone connection over traditional phone lines, such as digitizing and digital transmission, are already in place with VoIP;
Location independence. Only a sufficiently fast and stable Internet connection is needed to get a connection from virtually anywhere in the world to a VoIP provider;
Better and more economical integration with other services available over the Internet, including video conferencing and message or data file exchange during the conversation.

VoIP Experts In
Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks.
Internet telephony refers to communications services — voice, facsimile, and/or voice-messaging applications — that are transported via the Internet, rather than the public switched telephone network (PSTN).
The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.
