Net2Phone  Internet Telephony Software Questions

Firewall
This information should be provided to the maintainer of your firewall:
Net2Phone uses one TCP/IP and one UDP/IP socket on the PC. The UDP socket is used for starting the call and for exchange of voice packets. The Net2Phone servers connect to the TCP socket resulting in a TCP connection on a new, anonymous socket on the PC. The new version (5.02 or later) of Net2Phone allows you to specify the port numbers for both the UDP socket and TCP socket. By default, new sockets are used for each call. If you specify either or both socket numbers, those ports will always be used. To specify the port numbers, enter the following lines in the [CONFIG] section of your NET2PHONE.INI file located in your C:\WINDOWS directory:

TCPPORT =nnnnn
UDPPORT =mmmmm

nnnnn and mmmmm are the port numbers specified by your firewall administrator and must be in the range of 1 to 30000

General Protection fault in module Net2Phone.exe
If you receive a "general protection fault in module Net2Phone.exe," you should do the following:

1. Download and install a new copy of Net2Phone.
2. Close all non-essential applications.
3. Perform the same Net2Phone action that was initially attempted.

Net2Phone cannot open a wave input device
Make sure you have a soundcard, which is not an mwave sound/modem card (which will not let you run the Net2Phone application). If you got the error, and pressing cancel does open the Net2Phone application, you may have been using your sound card for something else and it missed the wave device needed to run the net2phone software. When you place your call, you will be able to hear the telephone party, but the telephone party will not be able to hear you. If you do not have a sound card, you will also receive this error message. And if you are running any other program using sound, you will also see this error message

"server 1,2,3...cannot connect to server"
If you are receiving the error message "Waiting for server 1,2,3,4..." ending in "Cannot connect to server," do the following:

1. Make sure you are connected to the Internet.
2. Make sure you do not have a firewall. (If you do, go to instructions on firewall)
3. Close all non-essential applications and try again.
4. If all of the above fail go to the config section in the Net2Phone.ini file. At the bottom, add the following lines:

pingresponse=60
setuptimeout=60

If this problem persists, it is possible that the internet connection you are using is too slow. Even if you are using a 28.8 modem, it is possible that you are not actually getting a 28.8 connection from your service provider. Check with your service provider on how to obtain a faster connection.

"Cannot initialize winsock.dll"
If you are receiving this message, Net2Phone cannot locate the file winsock.dll which is needed to make the connection to the Internet. Try the following:

1. Make sure that you are connected to the Internet. You can check this by browsing the web or checking your email.
2. Try moving the Net2Phone directory as a sub directory of your Internet connection directory.

Make sure you have only one copy of winsock.dll on your hard drive (usually in the C:\WINDOWS directory) If you have more than one, rename them to something like windsock.old.

"unable to locate dialer executable (3), check Cserve.ini"
Please contact your ISP's technical support as this is an Internet provider's issue.

CRC error when trying to unzip file.
Re-download the software and make sure no other applications are running at the time.

tcpman.exe not found.
This is an Internet error. Please contact your ISP for technical support.

Unable to connect to server (TCP Error: Can't assign requested address)
Make sure that no other applications are running in the background. Reboot and then make a call. If this fails, contact your ISP's technical support.

You are dialing an unauthorized number.
If you have not purchased a Net2Phone debit account you may only dial the numbers with 800 or 888 area codes in UNITED STATES ONLY (except for the nubers that belong to the phone company , for example: 800-555-1212), any other attempt will result in this error message.

If you have purchased a net2phone debit account and you are getting the error message: "You Called an Unauthorized Number", please check the following:

1. That you have enough funds available for the number that you are calling.
2. That you are dialing the number correctly (please remember that every call is routed from the United States , therefore you must dial as though you are dialing from the US. For example, to call a number in the US, Canada or the Carribean Islands you would dial 1 + area code + number. To call a nuber outside these places, you would dial 011 + country code + city code + number).

Your account is in use.
It is possible that the last time you placed a call it was not ended properly and the server still thinks that you are logged on. Please wait about twenty minutes from the time that you received the message and then try again. If the message continues to appear, email support@net2phone.com

insufficient memory.
If you received this message, please make sure of the following:

1. That you have at least 8 Meg of RAM
2. That all non-essential applications are closed.

If you continue to receive this message and are using Windows 3.x, run Memmaker through express setup (for help with this process, contact Microsoft technical support.)
If the insufficient memory message continues to appear, contact your computer vendor and request information on how to optimize your memory.

CPU and UNDER are flashing in the back display and interrupting the call.
This is an indication that your machine is not fast enough to use the Net2Phone program. It is possible that you have an older com chip. If you are using a laptop computer, turn off the extra power savers. (Try using the latest version of Net2Phone and see if it helps.)

Computer keeps freezing when trying to place a call.
Try redownloading the latest version of Net2Phone.

Program has performed an illegal action. Your computer will shut down.
This is a Windows 95 generated error. For information on dealing with this message, you should contact Microsoft technical support.

Will Net2Phone work with MIRO WAVE-CONNECT 34 mwave?
Make sure no other applications are using your soundcard. Net2Phone cannot be used with an mwave modem/sound card.

Does Net2Phone have plans to support Linux (UNIX variants)?
No.

I have two ISP's. When I run Net2Phone it defaults to one. How can I default it to the other?
Before placing a call you have the ability to log onto any provider you would like. Once you have dialed into the ISP you can then bring up Net2Phone and place the call.

How do I know if I have a full-duplex sound card and how do I make the computer recognize it?
Like a telephone, a full-duplex sound card enables you to talk and listen at the same time. Similar to a walkie-talkie, a half duplex sound card only allows you to speak or listen, but not both at the same time.

In order to use the full duplex sound mode, you will need to have a full duplex sound card with the updated drivers. There is a possibility that you might have a full duplex sound card, but without a updated driver Net2Phone will not recognize full duplex capability. These drivers are specific to the type of sound card you have. You can get the updated drivers by contacting the manufacturer of your sound card. Generally, the drivers will be available for free download from the manufacturers web site.

Further, when mkaing a Net2Phone call, you will notice the letters HDX or FDX on the Net2Phone screen. These stand for Half Duplex and Full Duplex.

The best way to know if you have a full duplex sound card with proper drivers is to click on the "phone" menu while Net2Phone is running and see if "full duplex" option is available. If the option is not available, you may try to contact the manufacturer of your sound card or your computer vendor to see if, in fact, you do have a full duplex sound card. You may only need to install new drivers.

Can I use Net2Phone if I connect to my ISP through a SLIRP?
Net2phone cannot be used with a SLIRP account.

Invalid Account/PIN
In the process of registering Net2Phone, you were asked to choose a 5 digit pin number for security purposes. If a pin number that you saved to your hard drive, when you first started using the software did not match the original number, it will result in a "Invalid Account/Pin" error message. You can ERASE it and reenter it to your hard drive by:

1. Opening up the Net2Phone software
2. Clicking on "edit" menu at the top of the program
3. Clicking on "erase pin"

You will be asked to reenter your pin number the next time you dial. Then you can enter the correct number and save that number to your hard drive.
