VoIP designed for your business
VoIP offers significant benefits to your business so its critical that you work with a business VoIP Provider who can provide you with the technical skills to optimise your benefits and ensure a hassle free implementation. VoIP operates under a number of different protocols including H323, SIP and IAX. In addition some VoIP Providers use their own proprietary solution, limiting the ability to capitalise on the wide range of open source hardware available in the market place.
SIP was created by the Internet Engineering Task Force (IETF) and gained prominence around 2002 when Microsoft selected it as the standard for VoIP providers who were included in the launch of Microsoft Windows XP or as part of MSN Messenger. Since then SIP has become the accepted standard for most end users with a proliferation of PC software,
More recently, the term SIP Trunks has been used by VoIP Providers to identify VoIP services that allow multiple inbound or outbound calls. SIP trunks use the SIP protocols that have now become the defacto standard for most VoIP services and hardware. A SIP trunk is in effect no different from any other SIP based VoIP service, it just denotes that the service is capable of having multiple concurrent inbound and outbound calls. All V4B VoIP numbers are SIP trunks , allowing our customers all the benefits of a SIP trunk but without the extra charges that many VoIP providers charge for this service.
Because VoIP converts data into small packages and uses the public Internet there are several technical issues that need to be addressed:
Delay/Network Latency is inherent in VoIP technology since the VoIP packets have to travel from the origination point to the destination through the end users own network and the public internet. Some of these delays are fixed by the laws of physics but delays within the end user network can be minimised by giving VoIP packets priority over other network traffic. Alternatively, for multiple users it may be advisable to have a dedicated ADSL or cable connection for the VoIP service. When VoIP traffic is not in conflict with other internet traffic the delay and network latency is not noticeable in voice conversation.
Packet Loss is simply where an individual packet has not arrived at the destination within the designed time frame and therefore creates a gap in the conversation. A single packet loss may have no discernible impact on the conversation but a larger element can make the conversation difficult to understand. Packet loss is often due to network congestion and within the confines of the end user network it is again possible to minimise this by proper network management.
Jitter is the result of variations in the delay during period of the phone call. This is countered by using buffering to store the VoIP packets at the destination prior to then being heard.
