What's the difference between a SIP Trunk and a SIP User?
One thing our customers love at Yay.com is how we let them mix SIP Trunks and SIP Users in our cloud switchboard. For example, you can make a call to a Yay.com number and send that call to both a SIP trunk connected to your on-premise PBX and at the same time send it to a SIP User; the first to answer the call receiving it.
SIP Trunks, also know as SIP Channels, were the original solution to transition hardware based PBX’s (Switchboards) away from analogue phone lines to a digital VoIP solution.
A hardware based PBX was that box in the corner of your office that your phones used to connect to. It then connected all your calls to the analogue phone cables coming into your building and let you transfer/hold calls etc - features nowadays better handled by a cloud based PBX like Yay.com
Although technically not limited in number of concurrent calls, historically, SIP Trunks were sold with a limitation of one call per “channel” to make them easier to sell and compare against a traditional analogue phone line.
Modern hardware based PBX's will generally let you connect to your VoIP provider via a SIP Trunk or a SIP User (See below), but this is quite recent, so you will often still need a SIP Trunk to make your on premise PBX (Now both hardware and software in form) make and receive calls.
SIP Users, also known as SIP End Points, are the accepted standard for connecting devices such as VoIP Phones, VoIP Intercoms and VoIP Apps to a cloud based telephone switchboard (Widely referred to as a Hosted PBX).
