Welcome to the V1 VoIP guide to SIP. SIP stands for Session Initiation Protocol, and here we will help you learn what SIP does, why it is used, and how you can earn recurring income as a SIP reseller.
What is SIP?
SIP is a signaling protocol used primarily for setting up communications within an IP network. The role of SIP within an IP communications network is to allow callers to easily locate their targeted recipients, and deliver session invitations effectively regardless of where the end users are located or what devices they are using. SIP is the de facto standard protocol for establishing, manipulating and terminating VoIP communication sessions.
What is a SIP trunk?
SIP Trunking is a service provided to businesses that allows them to connect their in-house IP PBX systems to the outside world – the public switched telephone network or PSTN. Without SIP Trunking, devices within a PBX can only talk to other devices on the same network. The ITSPs gives their clients a pipe or a “trunk”, which makes the connection to the PSTN, thereby exponentially increasing the reach and usefulness of their PBXs. V1 VoIP resellers are able to build on the traditional SIP trunk service and create entirely new business models; and these new “SIP Providers” are changing the face of the VoIP industry.
What is Hosted SIP (PBX)?
While a SIP trunk only caters to firms who already have their own IP PBX system built and are ready to hook up to the PSTN, the latest breed of SIP providers don’t require their clients to have anything other than phones. These ITSPs have their own PBXs hosted on their servers and allow businesses to make use of them, delivering VoIP services at extremely low prices. ‘Hosted PBX’ services come with built-in connections to the PSTN network, eliminating their clients’ need to purchase trunking separately.
What is a SIP address?
A SIP address looks just like an email. By default, the domain of the email – the part just before the “.com” will belong to the ITSP providing the service. When you use V1 VoIP, your SIP address will look similar to this: “firstname.lastname@example.org.” V1 VoIP also allows you the ability to change the SIP address domain to match the corporate email ID which your employees use.
At V1 VoIP, we offer SIP hosting, which along with the ability to make VoIP calls means businesses can get SIP accounts to distribute to their employees, which allows anyone using a SIP device to call them for free as long as they know the SIP address associated with that account.
