V1 VoIP Hosted PBX Glossary Terms and Definitions

V1 VoIP cloud hosted PBX glossary of terms and definitions for common usage

V1 VoIP will help you navigate all the latest terms and definitions that virtual companies will use. VoIP technology is always upgrading and evolving to meet the needs of customers and because of this, new usages, terms and definitions are always emerging. Virtual phone systems and those based on cloud-hosted PBX are evolving at an extremely high rate in the VoIP universe. But did you know that not all providers call items the same things?

When dealing with a virtual phone system, the main terms used are PBX, Hosted PBX and Virtual PBX.
PBX: PBX stands for Private Branch Exchange. A PBX system is simply a telephone system solely for your business. The system will allot a certain number of extensions for the private use of your business. Non-internet PBX systems are run by equipment kept by the business itself.

Hosted PBX: A Hosted PBX system is one that is made available through the internet. Unlike a non-hosted PBX system, your office won’t be required to host telephone equipment because the hosting company does if for you. This will significantly lower the cost while providing the opportunity for easy expansion.

Virtual PBX Phone: A phone with advanced features specifically designed for use with PBX systems. This can include intercom, caller ID, conferencing, call forwarding, as well as other capabilities.

Within these three terms are many others that are associated with it. From features to functions, V1 VoIP has alphabetized list of common PBX terminology:

ACD (Automatic Call Distribution): A system that allows representatives to speak to callers in the order that they call. If you’ve ever called somewhere and had an automated teller announce that “your call will be answered in the order in which it was received,” you have experienced ACD.

Answering Rules: Settings directing how to handle calls. Can include different types of callers (for example, those that are important and others which need to be blocked) or times of day (open hours vs. closed hours).

Auto-Attendant: The virtual secretary who guides your customers to the appropriate party. V1 VoIP offers several options for auto-attendants

Dial-By-Name Directory: A database that allows callers to use their phone keypads to dial the name of the person they want to reach (e.g. 76484 for SMITH).

Extensions: Telephones that are connected to the same line. In some virtual PBX situations, the term can refer to individual phone lines.

Find Me/Follow Me: This is an advanced V1 VoIP virtual PBX system meant to minimize missed calls. Both rely on forwarding callers to different numbers for the person who is being contacted (e.g. office and cell numbers). Some “Follow Me” systems go a step further by determining your location from your internet and phone activity and forwarding the call to the appropriate phone.

Internet Fax: The ability to send and receive faxes over the internet. V1 VoIP internet fax includes receiving faxes via email, so you can always receive these important documents even while you are away from the office.

Porting: The process of moving a phone number to a new telephone service. Contact V1 VoIP to find out about our porting rates.

Toll-Free Number: A number that is free for customers to call. These numbers can include different prefixes, such at 800 and 877.

True 800 Number: A toll-free number that starts with the number 800.

Virtual Number: A number that does not actually connect to a phone number. It might connect to a voice mailbox or automated messages instead. V1 VoIP can also forward virtual numbers to actual phones.

Vanity Number: A phone number that spells a word or a phrase corresponding to letters on a telephone keypad. A great example is 1-800-GOT-JUNK.

V1 VoIP Glossary of VoIP Terms

ACD (Average Call Duration)
VoIP (Voice over Internet Protocol)
VoIP is a specialised protocol used to transmit voice data over the Internet. It is also commonly used to refer to the act of transmitting voice, and the many related services that have built up around it.
ACD is a quality metric used by telephony providers to show the average length of a call made over their network. V1 VoIP has a high ACD which suggests that few calls are dropped or abandoned due to quality issues.
ASR (Answer / Seizure Ratio)
The Answer / Seizure Ratio is a metric used to measure the quality of a telephony company’s network. It is calculated by dividing the number of successfully answered calls by the total number of calls attempted. A low ASR may suggest a poor quality network, though it can be heavily influenced by user behavior since busy signals and unanswered or rejected calls count as failures. A high ASR ndicates a reliable network, since most calls that are attempted are answered.
Call Termination
Call termination services allow other carriers and telephony companies to pass their VoIP calls onto the PSTN so that they can be answered over a traditional phone line.
A codec is used to compress and decompress an audio signal before transmitting it over the network. There are a number of different speech codecs used by VoIP carriers.
PDD (Post-Dial Delay)
Post-Dial Delay is the time it takes to receive feedback after a user has finished dialling. This feedback can be in the form of a dial tone, a recorded announcement, or the call being abandoned. V1 VoIP offers resellers a low PDD which gives an improved user experience. Consumers are generally used to the PSTN’s short PDD and often react negatively when there is a long pause after dialling.
PSTN (Public Switched Telephone Network)
The PSTN is the network that makes up the world’s traditional telephone systems. V1 VoIP provides services that allow VoIP resellers to terminate calls onto the PSTN.
