Inclarity’s Telephony Bundles


Cloud Communications

Jargon Buster.

Business Telephony is a complex subject, you have digital voice, voice over IP, there are PBXs and IP PBXs, there is SIP and there is Hosted Telephony and Cloud Telephony. What does it all mean?

VoIP stands for Voice over Internet Protocol. In simple terms, this is when a voice call is turned into data and transmitted over a traditional IP network. This has transformed voice communications for businesses because it means you can hold telephone conversations over the Internet or a corporate IP network.

VoIP has become the preferred communication system for businesses. Rather than maintaining two different networks (a phone line and an Internet connection, for example), businesses can streamline their systems so that voice calls are all conducted through the desktop via VoIP.

Session Initiation Protocol (SIP) is the industry standard that lets VoIP systems and end-points communicate. SIP works in a very similar way to email: a header is sent along with the voice packets that hold key information about the call (such as incoming and outgoing phone numbers).

SIP Trunks connects a premises-based phone system with a network service provider (i.e. your external lines). However, rather than digital voice trunks they are VoIP services delivering voice over an IP connection. For your business, this means agility, reduced costs and the ability to add intelligent SIP services.

VoIP Phones (or IP Phones) are physical devices, similar to regular telephones, that connect to your standard IP network. They use either proprietary VoIP protocols or SIP to deliver calls to the device. VoIP phones are used for the deployment of Inclarity hosted telephony.

PBX stands for Private Branch Exchange. This is a telephone system used by businesses to support multiple internal extensions and to connect to a collection of external network connections. The PBX lets each user have their own extension that supports external calls and calls between internal extensions. A PBX normally provides additional call features such as hold, transfer, conference calls, as well as access to company directories.

An IP PBX is effectively a PBX (Private Branch Exchange) that leverages VoIP to support extensions and in many cases to connect to the public telephone network.

Hosted VoIP or hosted PBX is where the business telephone system (the PBX) is hosted either in a private or public cloud. There are two ways that organisations do this. Either a business will take a standalone PBX and host this in a datacentre for its sole use, or companies will use hosted VoIP services where they have an instance on a shared, multi-tenanted solution (such as Inclarity hosted telephony).

Hosted telephony, also known as cloud telephony, is where organisations access business telephony as a service. Effectively, the capability of the PBX is delivered as a service from the cloud providing comprehensive telephony directly to each extension (regardless of location). This solution lets organisations significantly improve the functions they require on a pay-as-you-use basis including advanced hosted telephony, collaboration, mobile integration and contact centre capabilities.
