Switching to VoIP: The Basics

If you’re thinking of switching to VoIP service from a traditional landline based Key, PBX, or hybrid phone system, you’re not alone- businesses of all sizes are beginning to realized the cost-saving benefits of computer/telephony integration. Switching to a VOIP phone is relatively simple- changes can be made quickly and easily, and there is usually very little equipment to purchase.
Whether you’re switching to a business VoIP service or implementing a phone system for the first time, here are a few things you need to consider:
Internet Connectivity
VoIP phone systems use the internet to make and receive calls- you’ll need to make sure your connection and your power supply can support system requirements. Generally, a steady, uninterrupted power supply and a high-speed internet connection are all that’s needed. Your connection should be able to support the added traffic that the system will create. Vendors will ask how many employees will be using the system, how many calls are placed daily, and take into consideration features like auto attendant and call transferring when setting up your internet connection to support your system. You may need to purchase additional routers or install a backup power supply.
VoIP Adapters
If you’re witching to VoIP from a traditional phone system, you can save by purchasing adapters for your current phones. A traditional phone fitted with a VoIP adapter works identically to a VoIP phone. Most adapters are less than $50 each, and are often available in bulk discounts for larger offices. In lieu of adaptors, you can also purchase VoIP phones, headsets, or microphones that can be connected directly to a computer and used in place of a traditional headset. Most business and residential VoIP service providers sell both VoIP-compatible phones and adapters.
VoIP Phones
Voice over Internet Protocol phones are slightly more expensive that VoIP adapters, but are a good investment if you plan to use the system for several years. VoIP phones are easy to use and install- they don’t take any special training to set up. Once installed, they work identically to traditional phones. Most VoIP phones cost at least $100 each, with many vendors offering steep discounts for phones purchased in bulk.
Switching to a VoIP system takes surprisingly little time. Once you’ve decided to make the switch, you can shop around for providers and compare prices for services and equipment. Most providers can also make suggestions about system configuration (i.e., if you need a faster internet connection) during this stage. Once you’ve settled on a service provider and purchased equipment, you can have the new system up and running in less than a week.

Please let me elaborate more on VoIP. Voice over Internet Protocol has been around since many years. But due to lack of sufficient and affordable bandwidth it was not possible to carry carrier grade voice over Internet Protocol. But since the arrival of low cost internet bandwidth and new speech codecs such as G.729, G.723 which utilizes very low payload to carry carrier class voice it has recently been possible to leverage the true benefits of VoIP. G.723 codec utilizes only 6 Kbps (Kilo Bytes/sec) which is capable of maintaining a constant stream of data between peers and deliver carrier grade voice quality. Lets put this way if you have 8 Mbps internet connection, by using G.723 codec you can run upto 100 telephone lines with crystal clear and carrier grade voice quality. I am also a user of VoIP and have setup a small PBX at home. Since I have discovered VoIP I have never used traditional PSTN service.
Dear readers, if you have not yet tried VoIP I suggest that you try VoIP technology and I bet you will never want to use the traditional PSTN phone service ever again. VoIP has far more superior features to offer which traditional PSTN sadly cannot offer.
Also It has recently been possile to carry Video alongwith VoIP by using low payload video codecs. I cannot resist to tell you that by using T.38 passthrough and disabling VAD VoIP can carry FAX transmission, but beaware FAX T.38 passthrough will only work when using wide band protocols such as G.711, a-Law and u-Law.
By using ATA (Analog Telephone Adapter) which converts VoIP signals into traditional PSTN you can also using Dial-up modems to connect to various dialup services. I wont go in to the details what VoIP can offer, to cut my story short VoIP is a must to have product for every business and individual.
How VoIP Works
When we make a VoIP call, a communication channel is established between caller and called party over IP (Internet Protocol) which runs on top of computer data networks. A telephony conversation that takes place over VoIP are converted into binary data packets streams in real time and transmitted over data network, when these data packets arrive at the destination these are again converted into standard telephony conversation. This whole process of voice conversion into data, transmission and data conversion into back voice conversation takes place within less than few milliseconds. That is how a VoIP is call is transmitted over data networks. I hope that now you understand basics of how a VoIP call takes place.
What are speech codec’s and what role codec plays in VoIP?
Speech codec play a vital role in VoIP and codec determines the quality and cost of the call. Let me explain you what exactly VoIP codec’s are and how they work. You may have heard about data compression, or probably you have heard about air compressor which compresses a volume of air in enclosed container, VoIP codec’s are no different than a air compressor. Speech codec’s compresses voice into data packets and decompresses it upon arrival at destination. Some VoIP codec’s can compress huge amount of voice while maintaining QoS which means use this type of codec will cost less because it will consume just a fraction of data network. Some codec’s are just not capable of encoding huge amount of voice they simply consume huge amount of data networks bandwidth hence the cost goes up.
Following is a list of VoIP codec’s along with how much data network bandwidth they consume.
* AMR Codec
* BroadVoice Codec 16Kbps narrowband, and 32Kbps wideband
* GIPS Family – 13.3 Kbps and up
* GSM – 13 Kbps (full rate), 20ms frame size
* iLBC – 15Kbps,20ms frame size: 13.3 Kbps, 30ms frame size
* ITU G.711 – 64 Kbps, sample-based Also known as alaw/ulaw
* ITU G.722 – 48/56/64 Kbps ADPCM 7Khz audio bandwidth
* ITU G.722.1 – 24/32 Kbps 7Khz audio bandwidth (based on Polycom’s SIREN codec)
* ITU G.722.1C – 32 Kbps, a Polycom extension, 14Khz audio bandwidth
* ITU G.722.2 – 6.6Kbps to 23.85Kbps. Also known as AMR-WB. CELP 7Khz audio bandwidth
* ITU G.723.1 – 5.3/6.3 Kbps, 30ms frame size
* ITU G.726 – 16/24/32/40 Kbps
* ITU G.728 – 16 Kbps
* ITU G.729 – 8 Kbps, 10ms frame size
* Speex – 2.15 to 44.2 Kbps
* LPC10 – 2.5 Kbps
* DoD CELP – 4.8 Kbps
Switch to VoIP Today and you will never want to use traditional PSTN ever again.
Thanks
