What is VOIP? Do I need a fixed IP address (No NAT)?
VOIP stands for Voice Over Internet Protocol. No - the service will support devices operating in DCHP (dynamic) mode or with fixed IP addresses.

How good is the quality and will it replace my existing service?
The quality of Internet calls has improved dramatically and is now similar to Mobile phone call quality - which can cost up to 30 times more. However, it is NOT recommended as a replacement for an exisiting landline service - but an additional service, with another phone number. Remember that we have no control over the quality of - and contention ratio applying to - the internet connection that you are using.

What do I need to use just-VOIP?

1. For PC to phone or PC to PC operation. you need a PC with the just-VOIP dialler (softphone software) plus Microphone/speakers (or headset).
2. For phone to phone operation. you need an SIP device - phone or adaptor - which connects to your router/modem.
3. Broadband or any high speed connection to the Internet
4. A just-VOIP Account or PIN

Can I use just-VOIP with my dial-up Internet?
Theoretically, it is possible, but we do not recommend it.

How do I sign up for an account?
You simply complete the just-VOIP account application and we will send you by e-mail, your Username, Password, Web ID and (if needed) the IP address of the service. You will need these three bits of info to simply set up your softphone or hard SIP device and to access the on-line management information.

When can I start using my just-VOIP service?
Your service is "live" when you receive your welcome email and instructions plus your Username Password Web ID and/or IP address. For PC to phone, you can start making calls immediately you download and install the software. Downloading over broadband, installing and configuration usually takes 20 minutes or less.

Where can I get the Softphone software?
You can in fact use many different types of SIP Softphone software. Currently, we recommend our own softphone available for download here because it supports G723 and G729 codecs which means the calls take less of the bandwidth in your internet connection.

How do I set-up the Softphone Software?
For set-up, please follow the installation instructions for the software, followed by our simple instructions here.

How can I get the recommended SIP telephones?
The recommended hardware devices are available through reputable distributors. We will not normally supply them to you. You need to order them directly from the firm or a recognised distributor.

How do I set-up the telephones?
By reference to the manufacturers' instructions. The only items of information you will need from us are the Username, Password and IP address of the service, which will be in your welcome email, after you sign up.

Do I have to use the Softphone Software you recommend?
No you do not. However, we will be unable to support any other if you have difficulties in using the service.

Do I have to use the SIP phones you recommend?
No you do not. However, we will be unable to support any other if you have difficulties in using the service.

Can I get an incoming number for my service? What does it cost?
Yes - there are UK numbers avaialble - currently at no cost. There are also numbers from USA and Spain, which will cost £2 per month each.

How do I make free calls to other just-VOIP users?
This service is available by dialling the SIP numerical "username" of the other user, with a 9 at the beginning of the number.

What if my ISP (internet provider) tries to stop my VOIP calls?
The justVOIP service has a protocol available called IAX which can be used to prevent ISPs blocking VOIP traffic
