VOIP Technology Services

Picking the right phone system for your business can be a challenge. Not only are there a number of digital phone systems to choose from, there are specific business phone systems designed for small businesses, large corporations, and everything in between.

Factors to consider include how many employees will be using the phone system, what type of business phone service is available in your area, and how large you expect to see your company grow. Determining this number will not only help you decide how many actual phones and extensions you will need, but will also help narrow down your search to only those systems that are the most suitable for your business.

Of course, there are several other factors to consider in addition to the number of system users. You should also consider how many employees you currently have, how many lines you will need (including lines for faxing, if applicable), future growth, compatibility with your current hardware or internet connection (if using a VoIP system), what phone services are available in your area, how much you can afford, your call volume, your geographic location, your level of technological know-how, and other factors.


VoIP Telephony

VoIP phone systems can offer significant cost savings as well as many other benefits. VoIP runs over Internet lines and routes your calls over a data network. VoIP systems provide comparable service to traditional or PTSN based phone systems- in many cases, VoIP systems use some combination of internet and landline connections to route calls.

How Voice Over IP (VoIP) works –
VoIP works by converting sound signal into a digital format. VoIP uses a computer network as a vehicle for communicating sound. With increasingly powerful application specific services emerging all the time, VoIP is not only the most technologically advanced communication system, but also provides a level of reliability and mobility that is unmatched in voice communication. With VOIP, your communications needs are hassle free, leaving you free to focus on growing your business.

Features and Benefits of an IP PBX –
  • The single biggest advantage of an IP PBX is for businesses with multiple locations.
  • With VoIP, any and all offices on a LAN or WAN can get the benefits of having a common office phone system. This sharing of features can enhance collaboration as employees at different locations can truly feel like they are part of the same organization.
  • If the callers are on the company network, the phone calls are free - even if your offices are located thousands of miles apart.
  • For network administrators, VoIP means they only have one network to maintain instead of two.
  • The Move, Add, Change (MAC) process also is greatly simplified, because almost all VoIP systems are configurable through a web interface that can be managed by the administrator.
  • As because multiple offices are seamlessly connected, they can share a single receptionist, auto-attendant, and voice mail system.
  • All remote users can connect to the company network via a Virtual Private Network (VPN). VoIP allows them to make phone calls from the road at no extra charge. All the user needs is a "soft phone," (software that lets a laptop function as an IP phone), a PC microphone, and speakers.
  • Essential phone system features like caller ID, call forwarding, simultaneous ringing across multiple phones, and other features are available in most VoIP systems.
  • VoIP also works with advanced Computer Telephony Integration (CTI) applications, such as ‘Call Center Management’ and other vertical applications.

VoIP Drawbacks –
The main drawback of VoIP systems is the network requirements, specially the installed LAN and WAN bandwidth. VoIP requires high bandwidth for clear messaging.

VoIP systems require more attention. Like any software application, your VoIP server will require occasional upgrades and maintenance.

Regular phones get all the power they need through the phone line, they continue to work if there is a power outage. In contrast, most VoIP phones need to be plugged into a power source to work and hence an UPS is very essential part of the install.

As the VoIP phones are very network-dependent, having a mix of digital and VoIP can be advantageous: it creates a more comfortable level of redundancy.

The key voice-over-IP requirements are –
  • Bandwidth - Determining how much bandwidth you will need for voice-over-IP in your office is your first step.
  • High Speed Internet -Need for a VoIP phone system is a high-speed or broadband internet connection. Choosing a low quality or underperforming Internet connection is a costly mistake which will degrade your call quality.
  • Quality of Service - You must decide whether voice traffic will be separated from regular internet users or if it will share the same network.
  • VoIP Equipment - There are many digital office phones, soft phones, headsets and telephone adapters on the market to choose from.
  • Power Failures - Voice over IP does not work when the power goes out so you should install a battery backup system and possibly a Power-over-Ethernet switch if your budget permits it.

VoIP Phone System Cabling –
Old infrastructure with CAT3 telephone cabling and RJ-11 sockets for traditional PBX will then need to upgrade the network cabling infrastructure to a CAT5e or CAT6 solution. The handsets that are used on a VoIP system are much like a PC, in that they rely on being connected to an IP network. They will have an IP address of their own. To guarantee that there are no issues with drop outs and stuttered speech, it is essential to install a structured cabling system that can accommodate the bandwidth requirements of every user on the network.

Therefore, to ensure that you are able to use such a service, a structured network is a must. Once installed, you will not need to worry about it for the next ten or more years. Since most new products depend on internet connectivity, you will be ready for any future needs.

Proviatek provides robust ‘Structured Cabling System’ (SCS) that integrates the voice, data, video, and various management systems of an office / building / factory. Please see our SCS install services under the ‘Network Infrastructure Services’ Section.

High-speed Internet –
VoIP uses the Internet to send and receive calls, so the most important thing needed for a VoIP phone system is a high-speed or broadband internet connection.

SIP trunking is quickly taking over as the preferred configuration for small and large businesses, government, and educational entities to receive both their internet and voice services. SIP is a protocol developed as an alternative to ‘H.323’. SIP trunks can interface with both IP and Traditional TDM PBX systems since they can be configured with a traditional T1 handoff. However, a native SIP handoff is the optimal and is the least expensive configuration. Some IP PBX systems do not charge a license fee for each of the SIP trunks connected to a system. Government and Educational entities with fluctuating call traffic are quickly taking hold of this new technology, which allows for a baseline number of trunks with a burstable capability.

Advantages of SIP Gateways–
  • Based on the logic of the ‘World Wide Web’ (WWW)
  • Dial plan configuration directly on the gateway
  • Translations defined per gateway
  • Advanced support for third-part telephony system integration
  • Interoperability with third-party voice gateways
  • Support of third-party end devices (SIP phones)


If such a connection already exists, your internet connection should be tested to ensure that it will be able to handle the extra traffic caused by VoIP in order for it to continue to run smoothly.
