1. What is Voice over IP?


Voice over IP or VoIP is a set of standards, CODECs, protocols and hardware devices that enable people to transfer telephone calls and voice data over a network or the Internet. The major advantage of voice over IP is the ability to place calls over a data network providing huge cost savings on hardware and implementation, interoffice and international calling charges, and long-term support costs.

    5. What is the rate of audio compression used with VoIP?


    There are several methods for audio compression used with VoIP. Some of the most commonly used are G.729, G.711, G.723.1. G.729 is the most prevalent standard of voice compression used with VoIP and typically compresses a 64 kbit/s voice signal to 8 kbit/s in 10 millisecond chunks, however, extensions exist to compress data to 6.4 kbit/s and 11.8 kbit/s with marginally better or worse voice quality respectively. In situations where G.729 is not the preferred method of transport such as for fax tones, G.711 can be used to transmit data with a 64 kbit/s stream sampled at 8000 times per second. Where compression is desired over quality G.723.1 can be used at 6.3 kbit/s and 5.3 kbit/s in 30 millisecond chunks.

    6. What is SIP?


    The Session Initiation Protocol (SIP) is currently the leading signaling protocol used with Voice over IP. SIP provides call processing features currently present in the public switched telephone network (PSTN). SIP provides SIP enabled end devices with the familiar dial tone, call dialing, busy signal, and tones associated with a traditional phone system. Additionally, SIP allows for peer-to-peer connectivity allowing for a simplified network core and increased scalability.

    7. What is IAX?


    The Inter-Asterisk eXchange (IAX) protocol used by the Asterisk PBX to route voice data over IP and provide in-band data and signaling that is used for voice connections between Asterisk PBXs and IAX enabled devices. IAX can be used to route almost any type of data providing great advantages when used with IP based video conferencing devices.
