When shopping for IP telephony services, it is incredibly easy to get confused specially between VoIP and SIP. Here is your guide to understanding when you need only VoIP Services and when to invest in SIP trucking.
What is Protocol?
A protocol is a way for two machines to talk to each other and understand each other’s data.
For two machines to exchange voice data, the machines need to be speaking the same language and that language is a protocol.
The protocol contains all the necessary information for the machines to communicate to each others on each end.
What’s Voice over Internet Protocol (VoIP)?
Voice over Internet Protocol is a service based on IP. VoIP is a form of internet telephony, so it can be contrasted with traditional Public Switched Telephone Network (PSTN).
VoIP permits normal voice communications, to run over a network that was designed to transmit data.
Essentially, it allows businesses to transfer from traditional phone line systems to an online system. This uses a computer network instead of typical phone lines to deliver a telephony service.
What is Session Initiation Protocol (SIP)?
If you are familiar at all with ordinary telephone technology, you can picture SIP trunking like PBX. SIP not only conveys voice but can also convey all types of media. SIP trunks transmit packets of data, which can contain voice as well as other data like video.
The difference between VoIP and SIP is in the ability to make just a voice call versus the ability to make a video conference call. VoIP service would allow the voice conversation, but it would require SIP to convey the video required for a face to face conversation over the Internet.
Most VoIP phone system providers offer SIP trunking so that customers can get everything they need in one suitable monthly service.
