Enable multiple device dialing

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To enable multiple device dialing

Open Network Connections.
Right-click the connection on which you want to enable the dialing of multiple devices, and then click Properties.
On the Options tab, in Multiple devices, do one of the following:
- If you want to dial only the first available device, click Dial only first available device.
- If you want to use all of your devices, click Dial all devices.
- If you want to dynamically dial and hang up devices as needed, click Dial devices only as needed, and then click Configure.
  
  In Automatic dialing, click the Activity at least percentage and Duration at least time you want to set. Another line is dialed when connection activity reaches this level for the amount of time that you specify.
  
  In Automatic hangup, click the Activity no more than percentage and Duration at least time you want to set. A device is disconnected when connection activity decreases to this level for at least the amount of time that you specify.

Notes

To open Network Connections, click Start, click Control Panel, and then double-click Network Connections.
If you selected Dial devices only as needed, the last multilinked device ignores the Automatic hangup setting, and a twenty-minute time-out is used for the last device.
If you use multiple devices to dial a server that requires callback, then only one of your multilinked devices is called back. This is because only one number is stored in a user account. Therefore, only one device connects and all other devices fail to complete the connection, and your connection loses Multilink functionality.

You can avoid this problem if the multilinked phonebook entry is an ISDN with two channels that have the same phone number.
Multiple device dialing is available only if multiple adapters are available on the computer.
If you select Dial all devices, dropped links in the multilinked bundle are not automatically reinitialized. You can force links to reinitialize by selecting Dial devices only as needed, then Configure, and then setting easily achieved Automatic dialing conditions which cause another line to be dialed. For example, set Activity at least to 1% and Duration at least to 3 seconds.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
