For a start, you must weigh the features of VoIP Internet phone service offered by the leading providers. There are several: there's Sunrocket VoIP and Vonage phone service; there's Packet8 VoIP service, Lingo, Speakeasy, Skype, Viatalk... then you must apply those features to your specific work environment and requirements. A VoIP phone service provider might offer the best of features, but they aren’t any good if you cannot use them. If your priority is to make a large volume of international calls, particularly to Europe and Asia, Lingo is for you. Lingo is also a good option if you travel out of the US because you can carry your US number wherever you go, and call the US at local rates. Lingo also comes with the lowest price for its range of features. Skype is different from Lingo and Vonage phone service in one important respect: it does not use a telephone as a go-between. While the Skype outgoing and incoming calls to/from a normal telephone is still to fan out in terms of dependability, Skype is the best option if you and your computer are inseparable and you have friends and family who are similarly inclined. For PC-to-PC calls, Skype is the best voice portal, and there is no price tag attached.
Voice quality and reliability
When choosing a VoIP phone service provider, if your first priority is consistently good call quality, and you don’t mind paying a bit more, consider Vonage phone service. Vonage comes with almost identical features as Lingo, but there is minimal in-call lag and echo experience. With Lingo, be prepared to sacrifice on the quality of calls. In the competitive marketplace, each VoIP phone service provider promises the best of service and voice quality, and you cannot be sure about the product. If you are investing in a monthly/quarterly/annual contract, it is best to settle for a VoIP service package that has a money-back guarantee behind it. Both Vonagephone service and Lingo offer trial periods, and Packet8 currently offers a 30-day money-back guarantee.
Installation Complicacies
You also need to consider how easy—or how difficult—it is to install the service from a particular VoIP or Internet phone service, both for business phone service and for home use. For a single user, the process is not half as complicated as for multiple users in an office environment. You must be sure that your savings from an economically viable service are not offset by the installation costs. For example, you must keep in mind that in an office environment, the VoIP usage will put additional stress on your broadband connection, and you might have to invest in increasing your Internet capability.
Broadband connectivity issues
Remember that VoIP broadband phone service needs broadband connectivity to be functional. Prior to reaching a final decision on a VoIP Internet Phone Package, you need to do a bit of research on the bandwidth that the service requires, and then ensure that your Internet service provider is able to match up. If you face regular power or Internet outages, you may end up paying for a service you cannot put to optimal use. In such situations, it is always advisable to retain your traditional phone service line as a backup.
Flexibility to opt out
VoIP Internet phone service is still in a nascent stage, and the future may bring in new providers with richer services. Therefore, it is important not to get into a long-term contract or commitment with any VoIP phone service provider; keep the flexibility-to-switch option with you.
Internet telephony is the future, and even some traditional phone service providers have conceded this by initiating VoIP service packages of their own. The choices are many, and growing. As the user, it is finally up to you to use the right package to your best advantage.
