For those who don't already know, SIP is a Voice over IP (VoIP) technology that enables phone calls to be made over a standard Internet connection. SIP (or the Session Initiation Protocol) is a signalling protocol that enables phones and other telephony devices to talk to one another. You don't need to understand any technical details in order to use SIP, but it is somewhat similar to the HTTP protocol used by your web browser to visit web sites such as this.
SIP trunking is a term sometimes used to refer to the provision of a SIP telephony service to end users. A SIP trunk refers to a single SIP account provided by a SIP service. Put most simply, a SIP trunk is nothing more than a username and password combination used to access the service. The account will have a range of features enabled for it, such as inbound and outbound channels, phone numbers, call forwards and many other useful features you won't get on a standard telephone line.
A key benefit of the technology for the consumer is the lack of proprietary software and so-called vendor lock-in . The technology is open and moving between SIP providers is quite simple and painless. Any hardware phones or software that you use can be used with any SIP trunk and changing provider involves updating just a few simple settings.
If you are completely new to SIP technology and just want to experiment or try out a test trunk, then you might be interested in our basic smartline sip trunk. It's only our entry level product, and doesn't include telephone support, but it's great for those just starting out.
