We are an international VoIP wholesale provider, here to help your business. Here we take a brief look at SIP trunking, and how it allows small, medium and large businesses to use VoIP successfully.
What is SIP trunking?
SIP trunking allows multiple end-users list of thailand whatsapp phone numbers to share bandwidth for their calls, by connecting nodes and switches. It brings a high level of scalability – as there are no physical constraints – and thus a reliable call experience.
SIP trunking allows employees to work in remote locations, perhaps in a regional sales office, or work from home. This would be impractical for a company using an ISDN-based system such as BRI or PRI as this would require additional hardware.
SIP trunking connects ALL the end-users, via the company’s PBX, to the Internet telephony service provider (ITSP). Not all of them can be active on calls at the same time however, so planning a telephony system means thinking hard about how many calls will be active.
How many SIP trunks?
A small business should start with, say, 5 trunks. Ironically 5 trunks may still be needed with less than 5 employees. This limits the cost of telephony to begin with, but allows the business to scale up. More trunks can be added quickly and seamlessly.
A medium to large business may well require hundreds of trunks, especially if the firm has a global presence with employees working in different locations. The IT budget will still benefit from being able to scale up and down the number of trunks.
A simple rule of thumb is to calculate the number of trunks based upon the number of end-users. At around 5 employees there should be an equal number of trunks. At 100 employees and above, there should be approximately 1 trunk for every 3 employees. There is an online calculator here [1] which allows detailed analysis.
While VoIP is an obvious decision for young, growing companies, SIP trunking is a must for any business using VoIP. Small, medium and large companies can all benefit from the quality, flexibility and cost of SIP trunking.
