So you have decided to switch your business phone system from
traditional to VoIP, but the lingo is starting to become confusing. What is IP
Telephony? What IP phones should you choose? Should you go with a Hosted PBX or
SIP Trunking? Should you choose IP phones or stay with your existing phones?
IP Telephony means taking advantage of the internet to deliver phone
calls. In other words, it turns voice into another digital application on a
data network. As a result, IP Telephony provides numerous advantages;
- Reduced cost
- Unified communications with streamline workflow
- Increased productivity with mobility
Do you know the difference
between IP Telephony and VoIP?
Although IP Telephony and VoIP are used interchangeably, VoIP is really
a subset of IP Telephony. While IP Telephony takes advantage of the Internet to
deliver your calls, VoIP is the mechanism used to transport your call over an
internet connection. While traditional business phone systems were designed to
serve workers at their office location, today’s worker often takes calls on
route to a client, when working from home, or while away on a business trip. IP
Telephony redefines traditional business telephone systems for today’s employer
by providing unified communications.
How Digital Communications are
Integrated into communication systems
Digital communications are a great step forward but they need to be
merged with computer systems (i.e. integrated) in order to deliver telephone
functions for voice, fax, and video.
Each communication requires a directory service and caller
identification, otherwise how can it be properly routed?
IP Telephony integration can depend on the size of the organization and
what it is used for, voice or data or both. A small business for example,
benefits from a Hosted IP PBX system that uses the Cloud to provide an
IP based (i.e. digital communications) business telephone system without the
purchase of hardware. This system is sometimes referred to as "Cloud VoIP”.
Larger enterprises must rely on an organization that understands VoIP
technology and protocols in order to properly integrate VoIP into their
existing communication system.
So what are Hosted PBX systems,
SIP Trunking, and IP PBX Hardware?
- Hosted PBX (private branch exchange) systems are
cloud based services. This means there is no need for capital equipment or
on-premise PBX hardware for your business phone system. These elements are
provided by your Hosted PBX Supplier and all you need are the handsets or
- SIP Trunks (session initiation protocol) are
digital phone lines that work with IP-PBX phone system hardware. SIP Trunking
(i.e. digital phone lines) connect desk phones to the call control servers and
can link remote sites via gateways into IP-PBX Hardware. These are some of the reasons SIP Trunking is
quickly becoming the new delivery tool for telecommunication services from
carriers. SIP Trunking also enables
softphones and computer applications to act as a phone client on an IP
- IP-PBX Hardware acts as the switchboard that
allows transfers and call routing, call holding, and conference calls among
many other features required for a multi-line IP telephony system. Simply put,
IP-PBX Hardware is a PBX that is IP enabled to handle digital voice
communications and data.
How do you gain the full benefits of IP Telephony has to offer?
Integrating IP Telephony into your communication systems is best
achieved with an experienced provider because of the number of ways Unified
Communication applications and IP telephony protocols can be merged. In other words, look for a professional
organization with plenty of experience.
