There are "Many Ways to VoIP".
1. From your PC using a Softphone
2. No PC - using ATA VoIP analog telephone adapter
1.
From your PC, you generally need headphones with microphone + a Softphone software. Most VoIP services (VSPs - VoIP Service Provider) provide free downloadable Softphones for your PC.
PC-based VoIP is possible using Dial-Up as well as HighSpeed Internet. (Most people will disagree with me on Dial-up.... but it is possible and I have done it).
Examples of VoIP VSPs with free Softphones are:
Skype
Gizmo5
Yahoo Messenger/Yahoo Voice
Google Talk
PcCall
Hotfoon
MediaRing Talk
Efonica
CallCentric
2.
To use VoIP without a PC, you will need:
- HighSpeed Internet
- Modem, Nat-Router, VoIP ATA box
- Regular telephone to plug into the VoiP ATA box
- VSP - VoIP service provider
Examples of VSP's that supply you with a "locked" ATA that only works with their services are:
Packet8
Vonage
LIngo
Examples of VSP's that are BYOD (bring your own VoIP device) and no contracts, or commitments:
CallCentric
InPhonex
Les.net
Voip.ms
I use a 2-Line Linksys PAP2T-NA or SPA-2102-NA (unlocked) VoIP ATA and configure Line-1 with CallCentric and Line-2 with InPhonex.
With BYOD VSP's I can swith providers at anytime with no penalties. They are all only pay-as-you-go. CallCentric also provides a free downloadable Softphone to use on my PC. So I can use a PC or my Voip ATA to make calls.
To configure your own ATA does take some technical ability. But it is worth the effort to learn - The savings are worth it in the long run.
*** VSP's that work over Dial-up:
It is possible to use VoiP over Dial-up (56Kbps) Internet.
Only a few VSPs will work over Dial-up speeds under 56Kbps.
The key to VoIP over dial-up is the CODEC they use to encode your Voice packets.
Most VSP's use high-bandwidth Codecs like G.711u or PCMU.
These codecs will require at least a HighSpeed Internet service connection of 256Kbps.
But if you use a "high compression" Codec like G.729a or GSM, .... you can use Dial-up connection for those VoIP services that support G.729a and GSM (and a few other low-bandwidth codecs).
Here are VSP's that will work over dial-up over Softphones on PC:
- CallCentric (supports G.729a and GSM)
- InPhonex (supports G.729a and GSM)
- Efonica
- PcCall
- Hotfoon
- Google Talk
Good luck in learning to use VoIP.
