Operating Requirements
FAQQ: How do I get started using LynxPhone? A: Download LynxPhone to your computer and save it to your computer. Be sure to remember where you saved the file (the desktop might be a good place). The first time you install LynxPhone you must configure a VoIP account. Q: Where do I obtain a VoIP account for IP-to-IP calls? A: IP-to-IP calls can be made free over the internet to other users on SIP (Session Initiation Protocol) networks. For example, users on the Free World Dialup, SIPphone, TerraCall, IPTel and Telezin networks (to name a few) can talk to each other. Q: Where do I obtain a VoIP account for telephone calls? A: IP-to-PSTN calls can be made by signing-up for an account with VoIP providers such as Vonage or Telezin. Some service providers will provide a real PSTN number so you can receive incoming calls, while other service providers only provide an account for cheap, outgoing calls. Q: It still doesn't make sense. What now? A: Let's use Telezin. Go to Telezin sign-up page. Enter the details and you will be allocated a new account. You will also select your own password. Use sip:YourNumber@telezin.net and the password you have selected in LynxPhone. Try calling the number 613 to test your new account. Q: How do I call other people? A: If they are on the same network as you (or you are with a service provider calling a telephone), just dial their number, or enter their account name. If they are on a different network, then type their complete account, just as you would do with an email address. Q: Can I call Skype users? A: No. Skype is a closed network. Everybody else uses SIP. Open standards encourage collaboration and competition, which results in better/cheaper services for the consumer. Q: When the softphone establishes a call, only one party can hear the voice. A: There are two possible reasons. First, a firewall or Network Address Translation (NAT) may exist between the parties. The other reason is an old half-duplex soundcard. Please upgrade to a full-duplex soundcard. Q: The other party hears an echo when I talk with them. A: There are two options. Turning on echo cancellation in the Settings/Preferences should remove this echo. Echo cancellation uses significant computation time and is sometimes ineffective on some machines. Echo cancellation is also not a perfect solution, so expect mixed results. Alternatively, try turning down the microphone sensitivity and the speaker volume. Q: How do I change the speaker volume and/or microphone gain? A: Up/Down arrows on the keyboard or the phone keypad control the speaker volume. Left/Right arrows on the keyboard or the phone keypad control the microphone gain. Q: What does the phone icon on the display indicate? A: It is an indication from your service provider than you have voicemail messages available. Q: Where is the Address Book? A: On Microsoft Windows you can use the Windows Address Book (WAB) to manage your contacts. You can usually find Windows Address Book in the Outlook Express folder. On other operating system, the system address book can be customized to make calls through LynxPhone using the remote control feature. Q: How do I make encrypted calls? A: Go to the LynxPhone Settings/Preferences and choose the Certificates tab. Generate a certificate for yourself by clicking the Generate button. The new certificate and corresponding key will appear in the list. The certificate is indicated by icon showing a black certificate with the tick. The key is indicated by the icon showing a set of keys. Export the generated certificate to a file by clicking on the Export button and save the certificate to a file. Send the certificate (via email) to the other party you wish to call. The other party should do the same process and send you their certificate. In the Certificate tab, import the remote party's certificate by clicking on the Import button. Specify that the certificate is a User Key. Specify the full address of the remote party when importing the certificate. The new certificate will appear in the list with the appropriate icon next to it. If both parties have the other's certificate, then the conversation will be encrypted. The padlock will blink of the display during an encrypted call. Q: What does the certificate with the cross on the display indicate? A: It indicates that the incoming call originates from an unknown/unverified phone. Some VoIP networks provide protection from unsolicted calls, or SPAM calls. Q: How do I get TLS working? A: Go to the LynxPhone Settings/Preferences and choose the Advanced tab. Specify the SIP transport as TLS. On the Certificates tab, import the domain certificate from a file given to you by the service provider. Specify that the certificate is a Domain Certificate. Specify the full domain as the address. The new certificate will appear in the list with an icon showing a server with a certificate. LynxPhone will require restarting to connect to the domain using TLS. Q: It doesn't work. What do I do? A: First, ensure you are using the most recent version of the software. If your service provider cannot help you and the FAQ doesn't either, you can contact us at lynxphone@bitlynx.com. Q: What other skins are available?
