Appendix I:
Using PING to verify
the remote site/
main office connection
Before connecting the Remote IP Feature Phone at the remote site, verify that an IP connection
can be made to the main office. This section provides a quick method for verifying the connection. If a
problem is found, you must correct it before installing the Remote IP Feature Phone.
Verifying the IP path to the main office can be done quickly from a user PC at the remote site using the
®
MS -DOS command PING. PING is used to send an echo request packet to the main office gateway
and verify that an echo response is received. Use the IP PBX's remote-access IP address for this test.
1. On the user's PC, bring up an MS-DOS window by doing either of the following:
• Click on the Windows
• If the user has an MS-DOS Prompt item on his/her Start Menu or desktop, click on it.
2. In this window, type ping followed by a space and the IP PBX's remote-access IP address and
press ENTER. You should receive a message similar to:
