VoIP means Voice Over Internet Protocol, where your telephone service is provided via the internet. If you have a reasonable quality Internet connection you can get phone service delivered through your Internet connection instead of from your local phone company.
Most existing phones can be supported directly by connecting them to a device (Analog TelephoneAdapter – ATA) that handles the voice conversion and connection.
The cost of VOIP service is lower than traditional landline telephony. This is due in part to economies of using the shared data network and partly due to monopoly pricing on landline services.
With VOIP, your phone number is portable. Anywhere you can plug into the network you can make and receive calls as if it were a local number.
VOIP also enables a number of features that come as standard offerings for your phone service.
If you have poor Internet quality then your VOIP service will suffer as it runs over that Internet line. Also, unlike landline phonesets that are powered by the phone line itself, if power fails at your residence, it will take out your router, your ATA and your VOIP phone service. No power means no phone service unless you have UPS equipment in place.
With a landline service, a 911 operator knows exactly where you are because you are hard-connected at a specific address. With VOIP you have portability and address variability so that the subscriber (you) must inform the provider (us) of any address changes. That way , when a 911 call is placed, the operator can refer to the correct registered information.
Some services at your residence may require a landline to function. Home security systems, door buzzer systems, etc. may be a problem. Please consult the providers of those services for details.
Members going to a VOIP service from a landline based phone will fall into one of two categories:
A. you want to keep your existing number have it ported to the VOIP provider
B. you will be dropping their existing number and using a new one provided by the VOIP provider
For all cases, a dry line install is required to replace the current service.
Our recommended process prioritizes guarding against you permanently losing your phone number and reduces the risk of service outage as much as possible.

This process is a bit of a tricky dance that we are constantly refining from our experience processing such requests for multiple members. Please let us know if you require any further clarification.
If you are using VoIP with a TP-Link TD-8816, TD-8817, TD-8840T, TD-8841T, TD-W8101G or TD-W8901G modem you may experience problems such as voice being received but not transmitted after a connection is established. This may be addressed with a command line setting change in the modem to enable this via telnet to 192.168.1.1.
ip nat service sip sw off
If the command is successful the following line will be returned:
nat sip v2 switch off
Note that this configuration change cannot be saved and so when the modem is rebooted or powered off, the command will have to be re-run.
On Linux operating systems you can access telnet by opening a terminal and typing in “telnet 192.168.1.1” at the prompt.
On Windows XP and Vista operating systems telnet can be accessed by opening “run” and the “cmd” command and entering telnet.
In Windows 7 and 8 you can bring up the command line by entering “cmd” in the search bar.
In any version of Windows you can also run telnet by installing and using the PuTTY free software application.
