SIP Address

A string that is assigned to a VoIP phone number(s) to identify it and allow it to be found and communicated with over the Internet using the SIP protocol. The string is similar in format to an email address and on the Telebroad system looks something like - 

A sip address is unique to each VoIP user and really sets him apart from any other VoIP user in the world. Phone numbers can be ported from one user to another but a sip address stays with a user for as long as he maintains his account. Phone numbers, of course,  are still more convenient to use. With Telebroad's TeleConsole account your phone number(s) are automatically assigned to your SIP address. But if you decide to use a separate softphone you can connect it and setup your SIP address as explained here.

Soft Key (Softkey) and Hard Key

Where a hard keys is a physical button with a fixed function, a soft key's function changes contextually or based on user's customization needs (the later are commonly referred to as DSS keys.) 

Physical soft keys are usually located next to a screen so a label with their current function can be displayed on it. Touchscreen soft keys are simply displayed on the screen itself. Business SIP desk phones, such as the ones sold by Telebroad, all use soft keys to provide users with various functions. An example of a hard key on a such a phone is the mute button - it always serve the same function. But a soft key button next to the screen can enable DND while the phone is idle or end a call while it is in progress.

Note that line keys are technically softkeys because their routing functions can be programmed by the user, but in our buying guides we list them separately from soft keys for the give users more specs to compare.  


A portmanteau for software telephone. It is a desktop computer software or a mobile app that duplicates the functions of a physical VoIP telephone, allowing users to make and receive calls over any Internet connection and enjoy many additional communication features. Besides its mobility advantages over an hardware telephone, a softphone usually also benefits users with a more convenient interface and easier access to messages and call logs. 

Telebroad's TeleConsole provides sotphone functionality and is available in both web and mobile versions. If you prefer to use  a 3rd party softphone refer to this article about how to connect it to your Telebroad phone number.


SMS stands for Short Message Service and is a synonymous term for text messaging. It is a technology that allows to sending text messages to and from mobile phone or VoIP platforms that supports it. Defined in the 1985, the SMS protocol allows for messages with up to 160 characters. Longer messages are spit into several messages with a total limit of 1600 characters. See also MMS.



Time-Division Multiplexing is a traditional telephone technology that allows simultaneous transmitting and receiving of multiple data sources over one signal. It works by splitting the signal into multiple short segments. Each segment carries information from a different source. The relevant segments to each source are assembled together at the receiving end. While TDM offers good reliablity and call quality it still requires dedicated physical phone lines. It has been steadily replaced in many organizations with VoIP which is cheaper,  more mobile, and much more adaptable to various business needs.  

If you are considering a switch from TDM to VoIP, Telebroad will help you keep your existing numbers and ensure the transition is as seamless as possible. There is no hardware installation required. SIP phones are optional or you can handle all your communication from computers or mobile devices using the TeleConsole. It is possible you may need to change your router to one which is VoIP compatible, but in many cases software adjustments to your existing router are possible. The entire system will run on your existing broadband connection. 


Unified Communications (UC)

An implementation of a phone system that takes various (business) communication methods and concepts and unifies (integrates) them under one platform. The unified methods may include (but keep evolving) phone calls, conferencing, email, internal company chats, PBX and extension dialling, SMS, faxing, queues an hunt groups routing and  more. The platform is also able to share users information such as availability status and contacts. 

While various systems may be at work on the back-end side, the user of a UC platform can access all his communication needs seamlessly from one software or app. Telebroad's UC platform is called PBXellent and the user software to access it is called the TeleConsole. The platform is runs as a cloud service that requires no special hardware.
